I have just 245k or so miles.

My 5 y/o likes the idea that it has gone to the moon (229k).

No work ever done on the motor.
Pulls strong. I generally get 26-28MPG despite a typical 80mph cruising speed, which seems like a healthy indicator.

Looks like rust is going to be the executioner for this one, as is the usual case in the northeast. It has held up better than most 20yo cars though.

I once knew someone with a 400k 450SE. Pretty good for a gas motor.
