I have to agree with 420SEL. There are beaucoup 300E's out there that have not been damaged. The prices have come down alot in the last year or two, making them even more of a bargain.
My 300E had experienced some minor panel damage, and had been repaired. I bought it anyway because a) it was only panel damage and b) I looked for a manual transmission 300E for several years. The car was absolutely pristine except for the fact that it had been repainted in places.
Odds are, the one you're looking at is an automatic as are 99% of them. There are zillions of them out there, don't settle for second best. These are fine cars, get a fine example.
