My opinion of McCormick is less than stellar. I started going to McCormick on the recommendation of friends, family and AAA. My recommenders swear by the service at McCormick, however in the past year, I have had two major repairs done by them (clutch and timing belt service @ 105k), both of which failed on me within 10,000 miles after the repair was done (done right, given that my car is well maintained and in otherwise good working order and I tend to drive like a grandma, these repairs should have lasted minimum 6x that). I've also had them start work on my car without contacting me and asking me if that's what I wanted. Another thing that potential customers should know is that unless you ask, the techs at McCormick do not present various options for repairing your car, and often 'over diagnose', meaning tell you that they need parts which are not necessary, or they 'under diagnose' meaning they blindly replace parts that they think are the problem without properly investigating the cause. For a ball join replacement they tried to convince me that I needed a whole new controll, when I was sure 100% that this is not the case. On the other side of the picture, I have reason to believe that my two major repair failures by them were a result of simply going by the book and not bothering to check surrounding parts/problems related to the repair that may have caused the need for the repair in the first place, and thus the problem would only happen again (as it did). In general they are open and helpful if you ask the right questions. However, Larry one of the head technicians, can be particularly rude and unhelpful. They will give you answers if you know what to ask, but they do not offer any explanation or options up front. They also completely stripped the threads on many of the bolts they had to deal with for the clutch job, which is uncool and ultimately unsafe. In a nutshell, their work is costing me an arm and a leg in time and money to re-do it right this time. I won't condemn them completely, as a number of friends and family who have been going to them for years have had great success. Perhaps they just don't do so well with my make of car, but I won't be going back there.
