I bought their service from shift.com, turn out its the biggest disaster of my life. My car is a porsche boxter, the mechanic is so unprofessional, he did not have the tools to set my car computer nor to measure the oil limit. It costed me 2000 to repair, and when I asked a refund (only refund of my package not compensation of repair), they gave whatever excuses you can think of to dodge. What a trash company, do not ever ever ever buy their service.
