What does a BMW 750IL 2001 go for these days with 50,000km on the dial?
Mint condition (Black on beige)

Since you mention kilometers, no clue. Here in the USA it could be $5000-15000 depending exactly where and when it is for sale.
Does kbb or NADA show data where you are? Not exactly a common car but you could try checking all the local sales listings, some like eBay let you see actual final sale prices (hopefully recent).
