Hey James ...! Hello Richard.
Early 230ies and nothing left for me to say...?
Yes, James' explanations are absolutely right.
VIN = ... 10-001028
body number is 113042-10-01026 (yes, one zero-digit less)
and production number is 027 I guess ...
(maybe I am wrong here). Look on the rear side (or right side if your are next to the left fender) of the hole (opening) for the engine hood hook.
From the VIN the car must have clearly been a stick shift and not Automatic.
Certainly it was modified later.
Carpet, seat covers and center rearview mirror (and horn pad) look terribly non-original.
BTW these amusing and confusing VIN-like 13-digit body numbers were used up to serial 001176 (or something close to that). Afterwards all pagodas had the well known paint code (etc.) plate that your 280 has as well, Richard.
Best,
Achim
