Hi all , nice points but Keith "With the additional reassurance of 100% satisfaction, or your money back guarantee", how can this work ? . If your mechanic leaves a dirty finger print on the car or you only completed 7 out of the 8 items they wanted done, then your customer is not 100% happy so therefore you would give them their money back and they go away happy (free repair) and leave you broke ? .What trade does this ?
As Tom says " you are only as good as your worst mechanic"

Regards
John
