Well, the saga continues. The car is a 1974 as far as I can tell. Stranger still, it also doesn't have k-jet at all, but looks to have d-jet EFI. It does have a very large engine that doesn't quite resemble a 4.5 from my memory, but I didn't see stampings on it in the usual places to identify it. Trunk lid and paint is original back there from what I prodded, so that fits, but the car seems to be a bit of a mystery. The badges on the trunk lid read 450SEL on the driver side and just 6.9 on the passenger side. Euro car correct?

Fair enough, I thought it might be kind of a freak. So I carefully checked all the vin numbers I could find in the door jams, firewall and a-pillar. They all match, including the ones stamped into the chassis, so I'm inclined to think the car really is a 74 and hasn't been messed with much. The paint is sun faded in such a way that I also doubt anything was ever repainted. Whatever the heck it is, the build date on the door jam is 10-73.

The vin reads something like:
116.033-12 01557
I searched some, but anyone who has a good link care to identify what all of that means?
My camera is kind of messed up, but I'll go through and see if any pics turned out vaguely decent.
