I requested a quote through Yelp and my request was sent to multiple auto shops. I chose this…read morecompany based on location and called ahead to confirm they could do more than just read basic codes. I had already done my own diagnostics and knew the car was running rich. I had ruled out the upstream O2 sensor, catalytic converter (both new), MAP sensor, and fuel injectors. I explained all of this to Matt before bringing the car in. He assured me they could perform deeper diagnostics with their equipment. After dropping off the car, Matt called and told me they had "confirmed" exactly what I had already told them, and that the next step would be pulling spark plugs--for an additional fee. At that point, I decided to go elsewhere. What I don't understand is why I was still charged the full $85 diagnostic fee, plus a $4 hazardous materials fee and $3 shop supply fee. Plugging a car into a diagnostic scanner does not generate any hazardous waste--no fluids are drained, no chemicals are used, and no parts are replaced. There's nothing about a basic scan that would justify a hazardous materials charge. That kind of fee typically applies when disposing of things like oil, coolant, or other regulated waste, none of which occurred here. In the end, I paid $92, wasted time and gas, and learned nothing new. The most concerning part was Matt admitting he didn't even know spark plugs would need to be checked as part of further diagnosis.

As a first-time customer, I brought my '79 El Camino to this shop because the car was idling high…read more After the service, I paid $500. They replaced my intake manifold gasket, BUT a P0200 engine code appeared afterward. I went back the next day and explained the issue. They told me they had left an injector unplugged and instructed me to clear the code, saying it would reset. The code was P0200, so I followed their instructions and cleared it. The code went away. The next day, I drove the car and it suddenly started shaking while sitting at red lights -- something it had never done in the five years I've owned this car. I checked the engine codes again, and P0200 had returned. I went back again and explained what I had experienced. They then told me that, in order to address the P0200 issue, they would first have to start by checking for vacuum leaks. This is where I became frustrated. P0200 is an injector circuit malfunction code, so I didn't understand why I was being told that I needed to start with vacuum leaks in order to address that specific code. I had already paid $500 for the initial service, and now I was dealing with a new engine code and a new shaking issue that the car had never had in the five years I've owned it. After declining any further service, I picked up my car from the shop. I then noticed a scratch along with a missing piece of rubber trim on my front bumper. I had not noticed either issue before bringing my car to the shop. The shop claimed they did not hit anything with the car, but they are also ordering me a replacement rubber piece. Overall, this was an extremely frustrating experience. As a first-time customer, I came in expecting to have my original issue addressed, paid $500 for the service, and left with a new engine code, a new shaking issue, and damage/missing trim that I had not noticed before bringing the car in. Based on my experience, I won't be returning. I would recommend that anyone considering this shop be aware of what happened to me and carefully inspect their vehicle before leaving the shop. Check pictures.

It turned out it was coming from underneath my supercharger! I talked with Audi before, not knowing exactly where the leak was originating from, expecting the worst ( A little history ..My wife's 2019 Audi S5 needed a thermostat replaced under warranty years ago (typical issue) and it required removing the supercharger at about $3k years ago / now it would be about $6K, per Audi!) Until now, besides tires and alignments this is the first time I ever took a car in for service... I also have a a 2005 911S. I guess I have trust issues. During the process, Joey communicated and sent pictures showing where the leak was coming from. When I picked up my car at the shop I asked if I could see the parts, and I recognized the parts... thermostat, water pump, PCV valve (weird looking PVC valve), hoses, Supercharger belt.... In conversations with him I felt he was honest, about $1/2 what Audi was going to charge, they are familiar with Audi and Porsche typical issues, and pointed my other known issues out. He gave me his honest opinion and he did not PUSH additional services on me as if it was urgent! Could I have found a less expensive place? Possibly, but I had piece of mind.... honesty, quality, and the car was done in 1.5 days. It has been about 3 weeks and no leaks.
