Before I decided to purchase a used Mercedes Benz from a private seller , I went to Jack's Tri-Star Motors, a local independent Mercedes Benz specialty shop, because they offered a Pre-Purchase Inspection for less money than the local Mercedes Benz dealer. I'm glad I decided to do this because they discovered several mechanical errors after performing a Free Diagnostic Check. They wrote up an estimate which I then presented to the seller who reluctantly agreed to pay to fix. I'm so happy I went to see Jack because I saved a lot of money.
Pros: service, price, honesty
