From a car-savvy customer:
"As someone who is a car person I give this place a 5/5. I usually like to work on my own car but if I lack the time or tools, I go here. They were kind, offered financing, but were not pushy about it. I feel that they are very fair and the price reflects the tools and the experience they possess. They also help with rides to rental places. Excellent service!"
