They saved me $700 dollars by actually FIXING something as opposed to just replacing entire assemblies. Thats the mark of an actual mechanic in my opinion. They think outside the box to save you money and they get the repair done quickly! I wholeheartedly recommend you give these folks a shot on your next repair!

What I'm not okay about is one of my side marker lights went out and brought them a set of bulbs to replace.

Overall I'm sure they did a good job on my oil change but I won't be coming back as I don't see any value for me.

"Take your money and get out of my face!" - German P. Rodriguez, Auto Tech Sercive Center CEO…read more This has probably been one of the most unprofessional people I have had to deal with. I went in because my car overheated and there appeared to be a coolant leak. German told me that it was the coolant flange and a coolant hose that caused the car to overheat. He quoted me $450. I thought it was a little steep given the low cost of the parts, but I didn't say anything since I needed my car ASAP for work. I picked it up after the repair and was surprised by the quick turn around. While driving to work? My car overheats again! I text German and he says he can take a look at it (never mentioning a diagnostic fee this time). Now he tells me it's the tempature housing and quotes me $320. After a little back and forth, he comes down to $290. Despite him having supposedly fixed the issue and already having charged me hundreds of dollars I agree... I assumed he would actually fix the issue this time. I was wrong. I picked up my car a second time. As I try driving to work... my car OVERHEATS AGAIN. Two tows and $740 later, and my car is still overheating. This time I call German, who starts saying he essentially doesn't know what's wrong with my car. I asked him if he can take a look at it again and he refuses. I then told him that he can look at my car again or refund me the $290. He then said he wouldn't do either. Eventually he says he would only refund me the $200, claiming he would keep $90 for a diagnostic fee. Mind you 1) he didn't actually diagnose the issue, 2) he had already included a $40 diagnostic fee in the original $450, and 3) never told me about a diagnostic fee the second time around. I told him that was unacceptable and explained that he didn't diagnose the problem. He still did not want to refund the $290 or look at my car and was extremely rude about it. After receiving a lot of attitude from German, I was fed up and told him I was going to file a complaint with the Better Business Bureau. Shortly after he shouted "Take your money and get out of my face!" and hung up on me. As far as the $450 I mentioned a refund initial but he said that was a different problem, although the reason I took it in the first place was to get my car fixed so as to not overheat. I realize he wasn't going to budge on that amount no matter how hard I tried to explain.
