This looks like a good deal.
For Sale: 2005 BMW 330 ZHP Convertible -- 24,000 miles, 6MT, autotrader, Georgia, $22,500
I think you're right on that. I called the seller several times, emailed through Autotrader and work email, but no response. Not sure why she didn't take the ad down ages ago...
And definitely, someone got a good deal.
