did u even spend $38k when you bought the car in 2003?!
Mods kill resale value
Summer heat, no A/C? Forget about it!
If I were you, I would sell most of your aftermarket parts on ebay or prime for REASONABLE prices (haha very much so different from asking price of car) and then try to sell the car as stock as possible.
Don't forget that the car is salvage title. I've looked into salvage title cars when I was broke but still wanted a fast car - People always make excuses when trying to sell a salvage title. "Oh not a big deal, hit a curb and put a few scratches....just a fender bender" Whatever your reason, someone smart like me wouldn't touch it with a 10 foot pole. Having said that, I still think NSXs have decent demand for salvage titles-selling at a DISCOUNT - not premium.
If you are handy with a wrench, you can make a bit off just selling the mods. Check out the Parts for sale on Prime- i check everyday, seeing if there is anything i can waste money on..haha
Good luck!
