The second picture is of a W126. It could be an '88 but the W126 coupes covered a few model years. Older ones were 380SEC and newer were 560SEC.

Look up a couple of 560SEC pictures (on eBay or on the internet somewhere) and you'll see cars just like the one in your picture.

Thats the car I'm looking for! What is it, and was a diesel coupe available?

I don't think they ever put a diesel in an SEC at least in this country. But if you could find one with a bad engine I cant see why it would be a hard coversion at all. In my opinion they are one of the most beautiful models MB ever made.one with a 617 engine would be a real treasure........

O.K. I'm not alone...wondered about doing the swap too, theres just something about that shape they got just right...

The proportions are near perfect ,rear window line is the best of any 2 door hardtot I can think of ,I belive it's the same as a 126 sedan but works real well on this 2 door.

I gotta think that a 617 turbo engine and tranny would bolt right in .Might have to use the diesel radiator , not sure if the fuel tanks fittings are the same but would bet they are similar . Maybe the transmission would be a different length. But it sure sound fesable.Autotrader.com would be a good place to start looking for one with a bad engine.........

just checked autotrader.com there's an 84 380SEC with front damage for 500 but must be a misprint as it has SE or SEL grille. There's an 85 500 SEC with a new interior for 3400 and a 560 SEC in FL for 3500 says it's a 96 but photo is a 126 ........

...and there's a nice article on the W123 body styles in the current Mercedes Enthusiast.

Shorter wheelbase, so has a different feel from sedan. Cost $35k when new. Some problems include lifter motors for the rear quarter windows which all seem to die, and the fact that ANY body / glass / or trim part for these cars will set you back plenty.

Mine is rust-free, but has had a load of mechanical problems since I bought it (for way too much) three years ago. At least there are no computers to go up.

Very low production, and I think maybe that's why Mercedes didn't bother to go in and fix stuff like the rear window lifters...maybe the most "collectable" W123 (see article cited above), but I wish I'd just found another sedan instead.

If you can find a copy, Frank Barrett's Illustrated Mercedes-Benz Buyers Guide has a lot to say on the various coupes...sadly, it seems to have gone out of print.

It's the car bhatt directed you to - a 1990 560SEC (W126).
