Finding out original specs

[Turbotechnic]

Hi all, I’m after some advice regarding original specifications. Is there a database I can use to find out the original spec of my e28 or will I have to go to a main Dealer? Overall I think my car is original and untouched but I’m unsure of the wheels.

Try a VIN decoder search on google for one, not sure how far back they go though.

Thanks, I’ll give it a go.
