I've been thinking about getting another MB, but have been out of the game for almost 10 years, so am a little rusty on what to look for on these cars. I have ran across a few 420SEL's on craigslist for $2500, and am debating on looking at them. One is a Black on Black car, and is perfect, except for car won't go into reverse when car is warm. The other car is a White on Palomino, and looks like it was garaged all of it's life and is well maintained. So what are the big issues I should be looking for on these cars if I go and look at them?
