mecum auctio prices

Did anyone watch the Mecum auction on the weekend I saved a few cars to watch and was stunned by some of the prices I was watching 4 68 and 69 dart gts cars. One sold for $27000.00 Thats was a 383 car.SOME OF THE OTHERS WERE RELISTED AS THE ONE ONLY HAD A $17000.00 BID.Im in a predicament of the cost of a resto on my swinger or selling it and buying a GTS all done?
