The 2000-2002 528/525 models are the ones that keep me up at night.

You really can fit that fridge in back and in Europe they are rated to tow quite a bit. I drove one of the corporate leases our company had when delivery my bosses to and from the airport in Munich or Zurich...I believe that one was a 2000 528 model and it was just as at home carving the back roads as it was bombing down the short stretch of unlimited autobahn at 130 MPH.

It was a simple car that left the impression of great driving dynamics, elastic power, excellent seats and simple controls...three dials for HVAC, Becker single CD radio and not much else.
