I think Joe hit the nail right on the thumb
When I first started looking at Crossfires, I was surprised by the low prices and the large number available.
However, even as I was searching I became aware that demand for these cars was increasing rapidly. I found several cars I liked, and they disappeared within a day of my choosing them as a "liked" vehicle. I also noticed prices climbing pretty quickly.
There are a lot of Crossfires out there, but most of them are now being offered at 2 to 3 times the KBB value. One private seller of a low-mileage car told me she had 10 people trying to buy her car, and was now offering it for high bids.
I think prices for these cars will continue to climb, as they only built about 70,000 of them over 5 years. They are FAR less common than Corvettes, and seem to me to be in the Jaguar class of exclusivity.
I'm glad I found mine now.
