We reached out to Arnold for a pre-purchase inspection. While six other places quoted us $250-$350 for a "comprehensive" inspection, we paid Arnold $100, which was a STEAL for what he did, even more than what the others promised. He spent at least two hours thoroughly checking the vehicle, test driving it and walking us through every detail so we truly understood its condition. We were looking at buying an Audi Q4 e-tron that had a damage report. A reputable dealership told us it was "minor" and offered to take it to the mechanic for our peace of mind. After browsing Yelp and reading the amazing reviews, we decided to come here instead and I'm so glad we did. I had already done my due diligence and familiarized myself with the vehicle and potential issues. I asked Arnold very specific, technical questions that I already knew the answers to. He answered every single one with clarity and confidence and everything I was expecting to hear. My husband stayed the entire time, and Arnold patiently explained everything while inspecting the car. You can tell he was that kid that made the auto shop his playground growing up. He's passionate, meticulous, and GENUINELY cares. What impressed me most is that Arnold will never pressure you. He won't tell you "don't buy it," but he will clearly explain what could go wrong and what it might cost to fix. When I pressed him for his honest opinion, he said he personally wouldn't buy it at the listed price but if we negotiated it lower, then it might be worth considering. That level of honesty is RARE. They are your small local auto shop but I would choose them over any flashy, grandiose service center any day. Their integrity and transparency make them stand out. Thank you so much, Arnold and your dad, for the amazing service. We ended up just buying a Tesla!

At that time, I felt it was a great option. This time, however, my experience was different. I am not sure whether it is because prices have gone up, but the tire looked repairable to me. Still, they told me it could not be patched and that I needed to buy a used tire instead. Since I was already there and the work needed to be done, I ended up paying $60 for a used tire. What disappointed me most was that I originally thought I would be able to keep my old tire and take it home, because I believed I could patch it myself and keep it as a spare. In the end, that was not how it worked. Their used tire replacement process meant they kept my original tire and gave me another used tire in exchange. So it did not really feel like I was simply buying a used tire for $60. It felt more like I was trading in my old tire, which did not even have a hole that obvious to me, and still paying $60 on top of that. The service was done quickly, but the overall experience left me feeling less satisfied than before. Next time, I would definitely compare prices and ask more questions at a few other shops before making a decision.on the car

Or if there were major issues to expect down the road, I could look into getting a new car instead of fixing this one. Ethan V. greeted me on his lunch break but made sure to listen to why I was there and gave me an idea of how long the wait would be and what to expect. Fortunately the car had a nearly clean bill of health. That is to be expected because I kept up with regular maintenance on the car. But they did recommend a few items to address to extend the useful life of the car: (1) Control Arms and Bushings had moderate wear, (2) my second set of tires had 3mm of tread, (3) the cabin air filter was a little worse for wear. My main concern, and why I brought it to this shop, was for hybrid red flags like battery issues. As Ethan explained to me, without taking apart the hybrid battery, it would not be possible to give a comprehensive health check for it. But since there were no error codes that came up that would indicate a problem with the hybrid system, the battery was still in good condition. He mentioned an anecdote of other Niros he's seen that that had 200k with the original battery to allay my concerns. He mentioned that I should also consider replacing the spark plugs probably due the mileage of the car. After giving me an estimate on what the cost would be if I decided to have them work on the issues, he said he could apply the paid inspection cost on the work if I decided to proceed in the next 30 days. Overall I had a great first visit with Electron and would consider returning if I decide to move forward with the recommended upkeep repairs.

Cesar said they skipped the rotation because my car "didn't need it" but tires should be rotated every 5k and I was due. My car still had OEM tires with wheel locks, and the dealership had neglected to give me the key to remove the tires, which I didn't know at the time. Bad on the dealer, bad on Electron, they almost certainly noticed and could've flagged it instead of the brush-off. Months later I had a blowout and couldn't change the tire because of that missing key. Would've saved me from being stranded. Friendly staff, mystery oil change, phantom rotation.

The job wasn't done properly at all. The leak continued after a small amount of driving. I hired another mechanic and the two of us decided to investigate and fix the leak. We took the cover off only to discover that there was no Gasket!! This is why it was leaking. I payed all of the money for the hourly rate only to have the problem not fixed. They had my vehicle for over a month, when I picked it up I opened the door only to discover there were parts left on the drivers seat. The parts were missing some bolts and nuts. I had to return to the shop and have one of the employees help me find the missing pieces. I put things back together myself, but what a blunder on their end. They installed a new Fuel Sending Unit as well, but that started to Leak and I had to properly replace and Install another Gasket. One last thing, someone at the shop was taking my vehicle out and about. I know this because when I left it there the first time my vehicle had a full tank. When I picked it up a quarter of a tank was missing. I thought maybe I was imagining it. So I filled it up a second time when I brought it back to them. Sure enough when I picked it up, it was down about a quarter of a tank. My tank holds a lot of fuel so it wasn't just them test driving it. This happed Twice. Businesses like this one have way too many vehicles in their shop. This is why these things happen, they are not able to do jobs properly because they are under pressure and doing too much. Start saying No we are too busy and don't be greedy! Pass on this shop and find yourself a Better automotive shop. I think the family is full of nice people, but the work is Unprofessional.

Project Import

Project Import is one of those rare shops. What separates them isn't just the quality of the work, it's the level of thought that goes into every decision. They don't just ask what problem you're trying to solve today; they ask where you want the car to be years from now and build accordingly. Every recommendation is made with the long-term goal in mind. I've brought them some complicated issues on my 1JZ-swapped E30, and at every step they've been realistic, honest, and incredibly meticulous. If something needs attention, they'll tell you. If something doesn't need to be replaced, they'll tell you that too. No upselling, no shortcuts, no guessing. Just real diagnostics and real solutions. What I appreciate most is that they refuse to take the easy route if it's not the right route. A lot of shops will get a car out the door as quickly as possible. Project Import takes the time to do things properly the first time. In the long run, that actually makes their work a bargain because you're not paying another shop to redo it six months later. Their fabrication, attention to detail, and workmanship are top-notch, but honestly the biggest value is the trust. When they tell me something, I believe it. When they recommend a path forward, I know it's because it's the best solution for the car, not because it's the most profitable solution for them. At this point, I won't take my cars anywhere else. If you're looking for a shop that's honest, highly skilled, forward-thinking, and genuinely cares about doing things the right way, Project Import has earned my highest recommendation.

The shop where I had the work done at rechecked everything and said there was no leak on the exhaust system. I came here for a second opinion. I called and explained the issue, and the person on the phone said to come by anytime and he'd take a look. I live very close and went right over. I met Jake who was very friendly and knowledgeable. He was well aware of the common exhaust issues on this model of car. He inspected the exhaust system, and also used a listening device under the hood. He concurred that there was no leak in the exhaust system. He said the problem could possibly be a blocked catalytic converter, but that the car would probably be running a lot rougher. While we were chatting with the car still running and the hood open, we saw some smoke coming out. He said whatever was causing that was probably the issue. They are a muffler and exhaust shop, not a full mechanic shop, so I didn't expect him to investigate any further. (I later discovered that the engine side of the PCV value hose was cracked and that's where the leak was coming from). I was only here briefly, but had a very good experience. I would definitely return if I needed any exhaust work done.

I thought the truck was just getting old and losing power, but with this new catalytic converter, all the power is back and the rough idle that it had disappeared. I have been doing business with muffler man for over 30 years now and have always been extremely pleased with their work.
