Wow, nice find. I would put the value at around 20k just ball-parking it. If you could get it at 15k it would be a no brainer. Hope whoever buys it keeps it as a stock collector.
I paid 6500 for my 131,XXX mile Mystic that needs work but for me it was worth it because mechanically it is fine but cosmetically it needs work. of course those 131,XXX miles have taken their toll on the chassis and it squeaks and rattles in certain areas but I'm identifying them and I know with SFC's and tq box reinforcement those squeaks and rattles will subside. I would pay double for this car had it been in as nice as condition as the one posted when you factor in the mileage then yeah I can see $15k because it is a unique car, even if the paint is more readily available than it has been in the past.
