Which Weels Fit What Models

[cpuken]

I'm real close to getting a 1997 528i but it currently has 15 inch weels.
I'm curious as to what wheels from other BMWs fit this car.
The dealer (used car dealer) carries BMWs, Mercedes, Lexus, etc. He has a few other sets of weels in his storage area but the salesman doesn't know which other wheels might fit this car. One of the helpers went to check the storage bin and I think he spotted some 17 inch wheels for a Z3. They didn't know and I don't know if they will fit. Help me out guys.

Sorry but the Z3 or any 3 series wheels is not gonna fit. Main problem is the offset of the rims on the 3 series. But a 7 series wheels would.

Wheels from 5,6 or 7 series are interchangeable.
