Personally I would be very cautious about this. With that few of miles, the car hasn't been driven regularly in any capacity. That may not be a good thing. Fluids and oils need to be circulated. Engines need to be run on at least a semi-regular basis. Mine has very low miles at 79K and even then I always make sure to start her up and take a spin around the block every few weeks so that it never sits undriven for too long.
However, for a collector that wants to keep this as a very special example of a mint condition "brand new" Supra that has defied time, somebody flush with cash could buy this up without even caring about the price tag. In fact, when you reach this level of collectibility, many interested parties will actually WANT to pay the higher price to secure the perceived value of the collectible.
I wouldn't be surprised if it sells near this price, but I would be shocked if it was from someone who wanted to build it out and drive it regularly unless they are just stupid wealthy and don't care about price. Mine is new condition as well with 79K and I will be listing mine for $17K next week.
