O.K., I'll admit I was pretty sceptical about all the 5 star reviews, but, being from out of town & country I decided to risk it. So, bottom line, they cured the issues with my 2006 GM diesel and did only what needed to be done, AND at what I consider a very fair price. They're also fun and personable folks. I can't think of any reason not to add another 5 star rating. . . . . . . Brian Schiele, Burlington, Ontario.
