I went here once because I had a Groupon. They told me my steering column was leaking and it needed to be fixed, the estimate they gave me was $1400. I took it to the Acura dealership for a second opinion and they assured me that there was absolutely nothing wrong with the car. I then told them what Car-X told me, they put it back on the rack, tested specifically for the problem with the steering column, and there was still nothing wrong. They tried to rip me off.
In fairness, I posted a similar review on Google and the new Manager of the store reached out to me to ask about my experience and offered to look at the car again, himself, for free...but at that point, it was too late. Won't go back.
