I disagree with some of the statements made
I would agree that almost no one wants to drive a S-chassis bone stock or keep it in a oe state long term, however there's no doubt that an unmolested example in factory shape is sought after by many, myself included. As the years pass, a clean car in stock form will increase in value, many buyers prefer a blank canvas to make their oun. The price for any S-chassis will continue to go up, and they will be sought after "collector cars" in the future, no doubt in my mind.
I don't care what my s13 will be worth years from now, I'm just an enthusiast with a passion for these cars and these are my opinions.
OP: Nice car, enjoy it!
