"Love them!! Very helpful and fair! Highly highly recommend! Good folks in here!"
"Great shop...great business. Great people.."
"After searching for tires at 3 repair shops, we reached here and were really impressed by the professionalism and amazing customer service by the business owner himself Michael. He ensured that we got the right tire, but also helped check other stuff while giving us pointers on how to maintain the car well given that this was an old car. Being students, this is one place I would ask everyone to consider if they want their car to be in good hands and at an affordable price. Thanks Michael!"
"Excellent, fast service at an affordable price by understanding, knowledgeable, and extremely capable staff. The only time I go elsewhere is for inspections; they always ensure my vehicle is fit to pass before I do so. Thanks guys! "
"Estimate for body work was 2-4 days and it took 14 days. Every day it was going be done 'tomorrow'. They did give me a loaner car for the second week. When I picked up my car, chips of paint had gone missing from the back bumper. It took another day to put some putty on that, which doesn't look great but I need my car back. They are probably good mechanics but I don't think they are set up to paint or do body work efficiently."
