I don't see a lot of the older 6 series here (sorry, I don't remember the body number). My neighbor has a beautiful '89 635i that is in immaculate shape but it has over 220k mi on it. He's selling it for a reasonable price but eventually this baby is gonna need an engine rebuild.
How many miles is high miles on these older bimmers and what would a worthy engine rebuild cost?
