Hi i am thinking of buying a 1975 Mercedes 280 SE its dark green 270000 ks and in good condition runs nice, i was also offered a 1984 Mercedes 280 SE in good condition which would be better out of both of those one has chrome bumpers other has plastic bumpers any help appreciated

Both great but very different cars, I'd pick the one in the best overall condition. If everything was equal I'd prefer the look of the '75. I'd try to avoid climate control on the '75, hopefully it has manual AC.

Thank you much appreciated i do like the look of the 1975 280

That this was mentioned at all, would suggest that it is the overriding concern!

What is the overriding concern you mentioned
