Pretty much all original (I believe) except the steering wheel and the upper dash part

To be honest I really don't know, that's how I bought the car, i didn't make any changes but the car is definitely a '73 build. Maybe my car is not as original as I thought...Did you modify your shoulder belts to the 74 style with rear retractors? Your carpets look more like a velour than the original German loop to me however. Unless of course you do have a 74 in which case the seats are pre-74 style.
You are correct the wood was refinished before I purchased the car and yes a little more red then factory deliveryBeautiful. But are you sure the wood is original? It looks a little more red than usual and in such excellent shape…
Looks just like the sport seats in my 128i. Same coral red too!
