Definately an M104. I have the same car (Well, mirror image - mine is LHD). In the U.S. it was badged the 300E 2.8. We only got the E280 for 1993, after that it was E320 only.

Hey Joe, is that your actual car? I wouldn't expect the windshield wiper to park on the left hand side of an RHD car? Whenever I'm in the UK all the 210 taxis (AKA all the taxis...) park the wiper over on the drivers' side.
