Allied Auto Works diagnosed my son's Chevy Tahoe on 12/30. Brought it in Thursday morning and had it back by 2:30. I was pretty worried about the car since it had an big-time oil leak. But Brett had it diagnosed and told me it was a minor issue - but to be safe - bring it back in a few weeks. Allied fixed a couple of other issues with the car the same day - I couldn't be happier with the speedy and courteous service. Glad I found them on Yelp - they are the mechanic, now, for this car. Treated very fairly with friendly service - and prompt attention to our car. The shop on Miramonte is exceptionally clean, too.
