Value inquiry Audi 100 2.2E Built 85

Moin guys, I have a question for you! Offers were offered to me a few days ago an Audi 100 2.2E 10V with 133hp. Engine identification letter is KZ. With 283tsd km. In a ”Gold”’ metallic. The Audi is completely original, but has its small beauty defects but no rust. The equipment includes the car: G-kat, color glazing, sliding/hub roof, power steering, central locking and a trailer coupling, as well as a beige velour equipment, fog lights, original Audi aluminium rims. He currently has no tuev, but would get what without problems. Therefore my question, in 2015 he would get an H-mark. What is the car worth ?
