As I understand it the 300SL 86-89 is the same/similar engine to the European '86 300 E class though someone more "in the know" may come back with the details.

If you get a proper Euro with a "non-USA'd" engine ( no CAT etc) you'll get a reasonable performance (for a cruiser that is) but if all the US emission stuff has been added I think it will be a crawler! ( In Europe the 107 didn't have a CAT fitted).

Cheers

Jim
