whats it worth

[fredh]

I have a 1973 P337G and its time to sell it but i have no idea what its worth so im asking for a little reality. I purchased this airplane 6 1/2 years ago my partner hasn't flown it in 3 years, and i have flown it less than 50 hours in the same time, heart attack didn't help things. We put a ton of money into the engines and props and realize we will only recover a portion of our investment. I have a friend interested in purchasing the airplane and want to price it fair with todays current value, but i also don't want to give it away. So any help would be appreciated: Approx times, 6000TT, rear 150 smoh w/new cylinders, front 100 smoh w/new cylinders, 150 both props, Interior leather 7/10, exterior 7/10, KMA-20, Garmin 430, KY-196, KNS-80, R-50V R-nav brand loran, KT-76A, Navomatic A/P w alt hold, PCD-7000-1 PS Engineering intercom w/cd player, Kign HSI slaved, De-iced, Complete logs, no damage history.
Thanks
