Seriously though, buy a used BMW M5 or Audi S6 with a certified warranty. Best deal you will ever get. Both are rediculous values as they will last forever and they drive like they were built to cruise at 150 MPH on the AutoBahn. Going 90 on the highway is like doing 55 in an american or japanese car. Just test drive one before you buy. The 2010 models are nice and around 40K locally.
Look for cars coming off leases and haggle. That's what I do. Had my last 2 German cars for 12 and 13 years respectively and My mechanic bought both of them from me they were in such excellent shape.
