I read some good reviews on Citysearch about those guys - so I've taken my 2002 Escalade EXT there a few times and after each time there I got more suspicious of their quality of work.
For my first service there they failed to properly repair my parking brake but blamed it on faulty OEM parts, supposedly all Escalades have that problem - okay... I paid for a full replacement, but the parking break is as shitty as ever.
They also failed to point out any other problem there was with the car (one light was out and they didn't notice...) they only worked on what I complained about.
The last time was the worst experience. The car seemed perfectly fine before the service and ever since it started making two new noises, one subtle knocking noise only noticeable at higher speeds, and then a squeaking noise supposedly from the AC belt (which they did work on). So I took the car back - TWICE - each time they redid the AC belt and the noise went away, but it returned - the first time after 2 days, the second time after 2 months... again, they blamed faulty parts and try to play down their responsibility for this...
I'm done with those guys - I do not recommend them! Now I have to start over in my search for a decent mechanic on the Westside...
Pros: Friendly service
Cons: Poor quality of work, no attention to detail
