So I was at the auto auction the other day and there was a pristine condition 1994 Mercedes S600. It got my heart racing, and I had to leave before I bought it (went for $3400 BTW). It got me thinking about owning a V12 big German sedan.
Obviously the BMW is a more driver oriented car, but ultimately both are fast and capable and very luxurious. Which is better in terms of reliability (obviously they are both going to be expensive to maintain), part prices/availability and ease of working on for an advanced home mechanic. This would be a second car to take long trips, shuttle the (future) kids to school and a chance to experience some V12 music. I don't mind a few things not working once in a while, so long as the car can get down the road more often than not.
