at the end of the e36 318ti life time bmw got desperate and dressed up the car with M3 parts. front airdam rear airdam and side skirts with ///m door protectors. so it's some what worth more. i'd say $6500 if it's in great/fantastic shape. how many miles?

also if you are into that sort of thing, you can swap in the e36 m3s S52 into it.
