After they screw up your car and do not fix it properly they will then (after a couple of days) tell you that the exact same problem is not caused by the same thing, and will not honor there warranty. Check out BBB complaints, there are 6(soon to be 7), all about the same thing. Don't be fooled by BBB rating of A like I was (will be calling BBB to find out why this is) dig further and look the complaints. Also be aware they use video taping to try to make false cause and effect claims. Be prepared to make your own video and recordings if you do have deal with them. It will help when you have to take them to court after they screw up your car.
