I used them just recently. My TT was running like crap, so they came and picked up the car in an enclosed trailer at no charge an hour away, they found some melted wires from the main wiring harness, replaced those,installed a new cam sensor, plugs and wires, tuned the car for two days, and sent it back to my house in an enclosed trailer. Very fair on price for the work that they do. The bill was around $1100 including parts and labor.
