Did a quick search. I see park place, motorwerks and sears imports being thrown around. If you stretch it to IL, these contacts came highly recommended in an ED friendy dealers master list over on bimmerfest:
Mark Wakeford Newbold BMW O'fallon IL
Jim Bauchwitz BMW of Orland Park Orland Park IL
Irv Robinson Motorwers BMW Barrington IL
Irv Robinson is a poster on e90post. His handle is 'IrvRobinson'. Maybe you can PM him with further enquiries. They have a website at
