I've been using master mechanics for over 15 years now. They are always prompt in returning calls, set up appointments quickly AB's always are reasonable priced. I highly recommend them! read more

First time bringing my 2019 Mazda for service here. Greg diagnosed my car's needs. It was done in 2 days as he said. Price reasonable for the work that was done and now my car is smooth as silk when it drives. Master Mechanic is my new service provider read more

Great place Been going there for years and have always been very helpful and fair. The only place o take our cars to read more

Just got my car back from Master Mechanics and Greg did a great job. My starter for my Honda Accord broke and I had to get it replaced which is not an easy fix. But in the morning I sent my car in, they ordered a part, got it repaired... ALL within one day which I'm very grateful for. The cost for parts and labor was expected but ultimately cheaper than other places I checked out. They also fixed my tail light, changed my oil, and fixed my tire pressures without me asking. Would definitely come back (knock on wood) if I had any more car issues. read more

Greg and Tom are honest and knowledgeable. Their shop is well known by the community in the area. Fair pricing and they run a tight operation. Brought multiple cars here both for repairs and maintenance service. read more

Did an excellent brake job on my Corolla in September. Quoted about ~$100 less than the dealer, and took about 2 hours start to finish. So far the brakes have been working great: no noise or difference in handling. They use aftermarket parts but the quality is indistinguishable from OEM so far. Thanks for the great service! read more

Honest and quality service! From diagnosis to follow up, these guys are great. My check engine light was on so I brought my car to master mechanics. I told them the situation and they stopped what they were doing to diagnose it/ check the code. Later that day they gave me a few detailed options and the associated costs. They were very honest about everything and gave me low cost options that other mechanics did not. Master mechanics saved me time and money- I highly recommend. read more

Great down to earth professional honest service. Never felt I was being taken. Used him for years.

Just had my first oil change here. These guys are such a breath of fresh air! Straightforward, organized, efficient, and friendly to boot. I appreciate that they've got all the records computerized and that I get a print-out w/ all the details plus mechanic's notes. Update 7 years later: still love this place. They always tell me what's going on and give me options rather than trying to hard-sell the more expensive thing. They even referred us to a Subaru specialist when there was a minor fuel line leak (reported by the computer) on our Subaru Forester that they couldn't isolate (and didn't charge us anything for the diagnosis). In comparison, the dealership simply told us that we needed to spend $1000+ to replace the whole fuel line. read more

I can't believe that Master Mechanics hasn't gotten the good graces of all Japanese car owners in the Natick area. I went here after hearing the all nice and praising things that my dad was saying about this place. My dad is no pushover when it comes to car maintenance, and he's been going here for years. I knew that my car needed a repair soon, but wasn't sure when. So I called up and booked an appointment for an inspection for the next day. I arrive and this guy behind the counter is super-friendly and starts up a conversation with me. So we talk idly while my car gets the check-up treatment. The inspection was pretty quick (or maybe it was just me distracted as the time passed), but another mechanic walked in and handed him an invoice, which they discussed first for a minute and then he immediately showed to me, explaining each detail. He told me EXACTLY how much time I had left to replace my axle (the major repair I knew about), and pointed out 2 other things I was unaware of: my rear tires were losing their life, but 1 of them could wait approximately 4,000 - 5,000 miles to be replaced, and the other one needed to be replaced ASAP. Those were his words exactly. I also discovered I had a minor oil leak. I mention this because I've gotten the car inspected at another place, and they clearly missed it. He didn't bother to suggest I fix it, instead explaining that it was a 10 hour job for 10$ of labor. So, he offered alternatively that I could gauge the oil myself every so often. He even explained a long and complicated technical process that could occur if the C/V boot broke while driving, since I was curious (in case I waited one day too long, trying to save as much $ as possible). No BS, just straight-up honesty and truth. No pressure to get anything done. He called up a tire store down the street and offered me a list of choices. I picked the Bridgestone Fuzion HRi. It's a good all-season tire, I'm happy with it. The tire came to 85, and he said with the labor, alignment/rotation and tax it'd be about $115 total. I was quoted at $40 for an inspection, so I was expecting to pay $155. 30 minutes later, he finishes the tire and rings me up an invoice, including at the top a handy list of all the things the inspection said. The invoice was for $100. I was pleasantly surprised, paid and thanked him several times. Since then I've gotten the axle replaced, and it was for $160 less than what he originally quoted me for. I'll definitely be coming back as a regular. They've won my service. read more

I've been taking my cars here for years. Whether a broken headlight or "leaking" strut, these guess always give me honest work for an honest price. They do all of my factory recommended maintenance as well as unexpected repairs. Highly recommended! read more

Just moved all my service to these guys for my 9 year old 153,000 mile Subaru and 12 year old 173,000 mile Honda Odyssey ... honest, trustworthy, reliable, fair ... and basically just good competent guys ... wow! Totally refreshing and what I need as I nurse my two aging vehicles along! So glad I found them! read more

I have relied upon Greg and his team to keep my cars running for over the last twenty years. I relied upon them to do the "new car" maintenance as recommended by the the manufacturer and in some cases an extra in-between service for oil & lubrication. I ran every car well over 150K miles and some over 220K. (Honda/ Toyota) Thank you ;-) read more

We've had all of our 3 Toyota's serviced here since we moved to town 20 years ago. We were referred by a friend who was living in Natick for many years before us. We believe the owner, Greg, and his partner Tom, have always been honest with us about what is going on with our vehicles. We have never comparison shopped; we have just been loyal customers, believing that our three cars represent significant business to him. We've run into Greg around town from time to time as our kids have gone through the Natick School system together. We like supporting this locally owned business and believe that we have always gotten good advice about our vehicles there. read more

After a year of getting a heat shield "welded" the rattling noise came back. After driving the car onto ramps and checking out myself there was just a screw that was holding it on. Very disappointing to not be able to get an honest service. read more

I appreciate the service that they give me. They always offer detailed explanations of what the problem with my car is. They leave it entirely up to the customer as to when things can get done. They are very honest about what needs to get done and the amount it will cost and looks to save me money whenever possible. i really appreciate their service and highly recommend them especially for those with foreign cars. read more

Went there for my 2 cars - never got a more expensive recommendation than what was exactly required.

Honda Accord: I wanted to like this place. But in 4 repair visit I feel I have been overcharged for parts & labor. I will now go somewhere else, before I'd go back read more

Never again do I plan to experience dealership repair service rhetoric and outrageous charges. Master Mechanics came highly recommended by a family member and several coworkers. The service was professional, prompt and AFFORDABLE! Thank you for quality service. read more

Have used Master Mechanics for over 10 years for servicing our Hondas. We have always had great experience, Greg and the staff is knowledgeable, flexible and trustworthy. I wish I could get my BMW serviced here as well. Definitely recommending to others to try them. read more

Tired of feeling that I'm getting the 'spiel' at the Toyota dealership, which always results in more extensive repairs money than I was expecting, I decided to try Greg Casten's place, Master Mechanics Automotive, for my next repair. It was refreshing to hear 'it was just the [fill in the part]. I have taken my car to Master Mechanics at least 5 times for different types of service over the past 2 years, and have observed how thorough their work is, and how knowledgeable their staff is. I highly recommend this shop to those who value the investment they've made in their car and want to keep it in good shape without paying dealership prices. read more

Allegedly, this place used to be great. I'm not convinced. A few months ago, I took my car there to get some basic services done (60k mile check in stuff). I asked them to take a look at some other things that were bothering me (shocks felt loose, the car shook when I drove it, etc.). When I came back, they mentioned nothing about checking the extra things...when I asked they said "oh yeah, we looked and didn't find anything wrong" in a manner that clearly said they hadn't actually looked. If that had been the worst of it, this place would have gotten 3 stars. However. The next day, I went to get new tires. I'd needed them for a while, so I went to another place in town to purchase and install them. When I went to pick my car up from the tire place, they informed me that I was missing 2 lugnuts from my rear tire, and that the other three were (get this) HAND TIGHTENED. As in, they could unscrew the lugnuts with their BARE HANDS. Now, I'm no car expert, but I'm pretty sure I can properly install a tire. Apparently the guys at Master Mechanics aren't so well-trained. But it gets better. When I called MM to talk to someone about what could have potentially *killed me* since I drive mostly highways to work every day, the manager was less than impressed. He not only barely apologized, but he even managed to imply that it was somehow my fault that they hadn't tightened the lugnuts. I called back a couple days later and asked to talk to the owner. The owner first started to tell me how sometimes even hospitals do surgeries wrong, so I should expect that sometimes things go wrong at the mechanic's. I stopped him mid-sentence and told him that mediocrity in the rest of the world does NOT excuse him and his employees from what could have been, at the very least, a pretty hefty lawsuit had I not been buying new tires the next day anyways. Eventually, we settled on him reimbursing me for the cost of a tire rotation and me informing him that I'd never let his shop lay another finger on my car again. Overall, this was an awful experience. I understand that mistakes happen, but this shop should have been bending over backwards to make it better. Instead, they blamed everyone else first and then eventually realized that they could have been in some serious trouble. I'd highly recommend going just a little further up the street to Neighborhood Wrench, where they actually know what they're doing and what customer service *really* means. read more

We've been using Master Mechanics for years and I highly recommend them. They're honest, efficient, and skillful. The owner, Greg, is great to work with, and he has a good group of mechanics working there with him. read more
