Well not really of this calibur. Usually about one every5-6 weeks of this size. But there are meets of about 15-18 cars all the time
For example tonight there is one in irvine. tomorrow night theres one in cerritos. thursday night there is one in Pasadena. Friday night there is one somewhere but im not goign to that one. Saturady night theres a huge party for all BMW drivers from bimmerforums.com. And Sunday is going to be this one wiht 60 BMWs confirmed so far plus other forums including exotics like lambos and also a corvette forum. And some supras.
typical socal scene for a week.Really mondays are the only empty days. There salways somethign going on.
