Agreed - if it's a one owner car (which was stated in the ad, but the claimed # of years owned didn't match up), you have a good basis point.
Assuming it's not rusted underneath, then you surely have to budget for another repaint. Can't believe that the customer repaint either a) matches the OEM and/or hasn't faded again - not to mention if the adhesive doesn't come off easy.
Also, should point out that this is priced at $6,250 obo. California car, not a bad deal at least from the pics. Note - there's also a Picasa page with pics of the undercarriage and the battery tray, etc. Some peeling on the vinyl roof, but the car looks pretty good.
