Blah blah blah more than 2 years (never mentioned any expiring time). Too bad, $250.00 to slap a cheap aftermarket muffler on my car. So much for integrity. His word is garbage (and this is just for a cheap muffler). Go somewhere else.

Definitely the most honest mechanic I've ever been to. I've lived all over the country and I've had…read morethe unfortunate opportunity to have to look for a new mechanic every couple of years. Before leaving Oregon to drive out here to Mass I had a complete checkup done on my truck, got a bunch of various work done, tires, etc. They told me I needed brakes, that they were at 10%, that it would cost $500, and grudgingly admitted I could probably wait until I was out there to get the work done. Well, I get out here and go to O'Brien's on the recommendation of friends who live here. He tells me the brakes are fine, no problems, that I could probably wait until I drive to the next place in the winter to do them (I was only here short-term). He charges me nothing for the inspection. I came back today because I'm about to drive halfway across the country again, figure it must be time for the brakes now. He could easily have done the work but instead, he tells me they're STILL fine and will probably be fine for a while, definitely until after I get out to the next place. Outrageously honest. It's been almost 9 months since the mechanic in Oregon tried to get me to do the brakes then. Almost a year! I might be driving back here in the summer and if so, I'm waiting to do any repairs until I get out here.

Recently purchased an older truck (so expect some issues) for use around the farm. My first trip…read moreto Worthington Garage was necessitated by a split rusted brake line. Cost to replace was very reasonable and turn around was quick. Second trip in featured check engine light and stuck front caliper. Resolution on the engine light (EGR code) involved a reasonable amount of trouble shooting labor and trimming back some rubber hoses (so no parts). And both labor and parts costs for the caliper were very reasonable. Will keep coming back.

I went to Greg's Auto Repair with a check engine light on my 2016 Scion. Upon arrival, I was…read moregreeted by the owner and he offered to check the codes. I had an engine and a transmission error code. A mechanic at the shop also checked fluids and found burned metal in them, not a great sign. They told me in the gentlest way possible it was time to get a new car. I asked what I owed them and they refused to charge me. Coming from NYC, I was taken aback to be treated with such kindness and good faith by strangers running a business. We talked more about cars and about some new cars to avoid that they are seeing a lot of problems with. Since this visit, I bought new car. It probably won't need work for a while, but whenever it does I know where I am going. Highly recommend this business for skill, integrity and trustworthiness. Thank you again Greg's Auto Repair.

TL:DR Greg's is the best around. Decent, trustworthy mechanics are worth their weight in gold…read more Background info: I turn my own wrenches. I work on my own cars and my motorcycles. In general, I don't use mechanics. But my wife's brakes started squealing, and she wanted us to find a good mechanic we could trust for the big jobs (Translation: she doesn't want to die if I mess up her brakes.) I called a couple of friends, and they both recommended Jeff at Greg's. I can't say enough good things about Jeff and his crew. I called and asked about replacing all 4 rotors and pads. Got quoted a very good price, and scheduled in for a Tuesday. Jeff called a few hours into Tuesday, and let me know that the front brakes were fine and didn't need replacing. I'd forgotten that we just replaced them not that long ago, and they didn't have many miles on them, just rust. The rears needed replacing, but the front just needed the rust ground off to stop the squealing. Now, a lesser mechanic would have seen the brakes were fine, and replaced them anyway; we'd have gotten what we asked for. Jeff doesn't roll that way. He fixed the actual problem, and it cost half of what we were quoted. Another note, the rotors he sold us are quality rotors. Ceramic coated so they won't rust after 5 minutes in the rain (unlike the old rotors our last mechanic installed!) All in all, Jeff and his crew are top notch. Honest, reliable, with a great reputation. 5 Solid Stars!!!

This place is the BEST! My sister and I went in and told Doug what we're looking for and how much…read morewe could spend. It's a vehicle that's not all that commonly available in this part of the country, and our price limit was right at the limit of what would be reasonable. He listened to us very carefully, asked lots of important questions, then set out on what can only be properly described as a "quest" -- and FOUND exactly what we were looking for! He was able to negotiate a great deal on it for us, then brought it back to the shop. This is where it gets even more wonderful, because the shop is known for being owned and operated by a mechanic with a sterling personal reputation and professional credentials, having trained in a shop up in Guilford, VT that is literally known as the very best one in the whole area. They assured us they'd go through and fix anything and everything on the vehicle that needed tweeking or repair before we picked it up, to make sure it was up to THEIR standards of excellence -- and that the price would not go above our limit even if they had to eat some of the cost. They explained this is because they shopped for the vehicle with their mechanical expertise, so if it cost more to fix it was that they'd assessed it wrong and should make good on it. Well, long story short, we took delivery of exactly the used vehicle we wanted, in perfect shape, looking like it came off a showroom floor, and it's everything we could have dreamed and hoped for. In the process, we found a mechanic we'll use and trust from now on, and made friends to boot! It's not easy to find a really superior mechanic and shop that has a personal value system based on ethics of doing what's right. Green River Auto is that place! And if you want a used car, I honestly do not see how you can do ANY better than you will if you go talk to Doug there. If he can't find it for you, it's not available. I've lived all over the country, from Texas to California and back again, and I have NEVER found a shop like this one, and never even imagined a person like Doug existed. He's literally come up with a whole new wonderful way to buy a used car you can count on, rely on, and be overjoyed with.
