The original hero car from the first movie is still at Warner Brothers. Warner Brothers unlike Disney or Universal really take care of thier vehicles. You can pay for a VIP tour and see the Batmobiles they have in their warehouse at the studio. I know they have the 89, maybe a Returns, a Forever, B&R and a Tumbler. The MTV car that was given away was a promo car made for the first movie, that car is now in a Museum in Roscoe IL, named Historical Attactions. There were a handful of Batmobiles created to promote the first film. Jay Ohrberg did the work on the vehicles for the second film and Jay made a good number of Batmobile replicas for museums and promotional work. Then other builders have gotten molds or made molds, so there are a good number of 89 Batmobiles out there.
As for this auction, the photos suck... who would ever spend that type of money with a listing like that?? I'll have to see what some of the batman websites are saying about it.
