Beware I paid cash for a used Mercedes on May 21st, 2013 . I was told that it had a Nationwide 90-day / 4,500 miles Powertrain warranty so when the transmission, torque and valve body failed on June 3rd, I felt confident that Brian would take care of things, as he had smoothly promised to do. As an aside, let me explain that the Powertrain cover that they offer is merely a piece of paper from a warranty company that has very bad internet reviews and very small print denying liability for any pre-existing condition. So, if you think about it, it is an absolutely worthless piece of paper. Well, it transpired that Brian had not even purchased the warranty cover for my vehicle so when I called him on June 3rd to ask him where to tow the vehicle he advised me to take it to my own repairer. He also assured me that the warranty company would reimburse me the cost of car hire while the vehicle was being repaired but that I must arrange and pay for the rental vehicle. He then purchased the warranty cover, effective June 4th, 2013. Naturally, the warranty company denied liability for the claim and I have now incurred almost $10,000 in expenses to this date. The warranty company charade took over two weeks to resolve so my vehicle has been in repair shops for 36 of the 47 days since Brian cashed my check. It is still unrepaired and I have had to rent or borrow vehicles for this entire period. United Auto Group has given me ZERO assistance
