NADA Values ..85 QV, GTS vs GTB

Setting in the Airport waiting on my flight, I decide to google NADA pricing on a Porsche 911 for sale in my area that I believe is way overpriced. Sure enough, it says this 88 Carrera is worth $52,000. So I decide while I'm looking I may as well check Ferrari gideline pricing. Says that High End for an 85 308 QV GTS is $87,200 while the same car in GTB is worth $78,000??? Think something is amiss with their valuing system.

 

Thanks Dave. Yeah, it's pretty obvious they put someone in charge of valuing these cars that hasn't a clue.
