The folks at Car-Doc are great communicators. They are honest in their assessments and don't try to sell services that they wouldn't do to their personal cars.
In my case, with a 100k plus miles on my CTS, there were several maintenance items recommended by Cadillac. The options were explained in detail and I was given an honest assessment on what would happen if I did or didn't do these services...no pressure, just honest communication...and a fair price
I wouldn't take my car anywhere else.
