My dad knows a cop who bought a 300SD just about new, maybe 2-3 years old. He only kept it for a year because it would never start in the winter, and the dealer couldn't figure it out. So after screwing with it for a year he got so fed up, he traded it in. The dealer gave him a good deal on a 300E to smooth it over and not lose him as a customer.
Even the old cars had a lot of problems, cars=problems.
