Wonder if the members who purchased an extended warranty with their CPO SLK can tell me if they received any paper work specific to the warranty. The only documentation I have is a $2,000.00 charge on my bill of sale. It doesnt even show that it is two additional years of coverage. The salesman assured me not to be concerned because the warranty would be "in the computer" if service was needed. However, I would think that documentation as to terms of the warranty, (start date, end date, mileage) would be given to the purchaser.
