At that price, I'm not surprised. As nice as the car is, it's not perfect. If you're asking $15,000, it had better be perfect. It's more an $8,000 to $9,000 car.
Was sold at auction not that long ago, 02/15 for $8925 jaunty75... so you're right on the money! http://www.classic-carauction.com/auction_results_details.cfm?pagesubid=54&auctionid=7334
Wow, but really unusual and rare, my unc had a 70 catalina, non-wagon, and just was something about it I liked alot. Somebody with a burning desire for such a low-mileage example, might jump on it. Esp for as few a bones that money is for some, nowadays. Especially me, lol, I would love to have it. Like the color, too.
Money to burn Gonzo Tex64? Here's a deal on a really nice 1970 Pontiac Catalina wagon... for a cool 25k. This is the one I would love to have...
