Guys I got a set of rims off ebay for my S320. They will not tighten down all the way! The bolts need to be like 1/4 " shorter. So is this nornal or did I get screwed. Its being hard to find this 1.5" bolt. Any ideas?

Yes.

The portion of the wheel that the bolts pass through is apparently a bit thinner with your new wheels than the ones you took off your car...so the bolts then protrude further and are now too long.

Get shorter bolts...and hope you didn't hurt anything by running the wheel bolts into other parts buried in the rear wheels.

Steve , Thanks - thats good to know. And they only had put on the front two before figuring out something was not right. So on with the surch for shorter bolt.
