I kind of have to disagree with you Kelly's (kind of). I do think cars that are this much deserve more respect. A lot more expensive cars out there than the one in discussion, Rolls Royce Phantoms, or the Silver Ghost. When you think about it, cars going for big amounts isn't too insane. After a house, to the average household, it's the biggest asset. (Unless you're rich, then a yacht, etc). I don't think it hurts the hobby too much. These are 1 of 1 cars, not your "average" Cuda or Challenger. Prices will always be high for our cars they didn't manufacture many. It's like basketball shoes or custom beds, prices are higher. Not many people need 34ft beds or size 20 shoes.
I can't see 318's or 383 cars going for millions, doubt they ever will, perhaps when flying cars are in use but that's understandable. There are E-Bodies then there are E-Bodies, expensive E-Bodies. Which with one-of one options deserve to be pampered and higher sort after.
