http://www.autosource-online.com/ While looking for used BMW's and porsche's I always come across Auto source. Is this a scam or what? Last month they said they had a 1999 Z3 w/ 4000 miles, rear panal damage, for $13,000 . It was in Tulsa OK, so I called the # on the add and left numerous messages to no avail. Anyone with info please post. Thanks in adv.
