You should post more info on this item for sale. This is clearly not an OEM headlight. So if you want to sell, a buyer would need to already have one that matches on the other side.
From the e30 M3, evolved the e36. They were "Keepin it Real" when they introduced the 318ti ClubSport in '95 and the 318ti Sports from '96 to '99. After that... well nothing else really matters.
