'Cause You Ain't No Aeroback Girl

It keeps coming up for auction. What's the matter with this Cutlass?

I wrote about it last year but Jalopnik found it again on eBay this year. It sold for $6,336, which is almost the number of the beast, right? I'll remain fascinated by the aerobacks until the day I die or until the day I get drunk enough to buy one off eBay in the dead of night.
