I've been trying to find an e28 for a few months now with no luck. Recently I came across a car for sale in Florida by a dealer named Miami Beach Collection. Unknowingly, this dealer has somewhat of a reputation. Because the vintage BMW community is pretty close knit, I thought I would post feedback from the e28 guys here in case you were interested their inventory.
