I've got 4 15X7" OE e36 bottlecaps for sale.
One of the rims is only two years old, because I bent a rim and couln't afford aftermarket wheels at the time, so I bought a brand new OE wheel.
***The rarest thing in the world, a two year old wheel from a car that ceased production six years ago.***
The other 3 are as old as the car (1992)

2 have Pirelli P7000s that are pretty much gone (one is corded)
2 have Pirelli P6000s that probably have a good 5-8K left

I was keeping these as spare, but my fiancee is moving in shortly and she doesn't appreciate the greasy aroma of car parts as much as I do.

Come and pick them up in SE Houston for $50 or some beer, or lunch, or a spin in your car.
If I like you I might give them to you for free-ninety nine.

I'll also drive these to pretty much anywhere in Houston if you really want them, but you're gonna have to make it worth my while. :cool
