I was being a bit cheeky about the "needing to sell the car to buy a kidney" bit but these types of cars are both what a seller is willing to accept and what a buyer is willing to pay. It is like that for all specialty/classic cars.
Having said that, I do stand by the BAT comment. Why would you want to fight over a car with your money when you can find a private seller. Frankly, if I can pay $16K for something others are paying $30K for, I'd happily keep my money. If you are willing, you can find deals. You just need to be mindful of what you are looking at.
