Given the comments made by those who have seen the car (specifically
here), it seems as though this is a relatively unmolested early-VIN survivor that was owned and maintained by someone without the same appreciation for originality that most in the hobby now bring to these cars. At this price (high), the 12v conversion, lower door trim and poor quality repaint call more attention to themselves than if the car were priced more realistically.
The local market for these cars is small. As with any asset to which the market has shown little interest, you need to modify your strategy in order to increase the product's appeal. In this case, you have three choices:
1. Do nothing -- Wait for the right buyer or advertise the car in 02-heavy markets (i.e., Los Angeles, San Francisco) possibly with an offer of free or subsidized shipping.
2. Reduce your price considerably. If I had seen this car for sale several months ago, I might have purchased it at a price more in-line with the market.
3. Invest in the car. Give it a proper paint job in its original colour, some healthier looking tires, refreshed suspension bits, etc. Given the extremely low VIN, a thorough sorting of this car could potentially pay for itself and provide you with more net cash than the previous two options. This strategy is used to great effect with slow selling real estate assets.
Hope that helps.
