With age comes wisdom ^^^^. I regret selling an 80's model Steinberger and a '58 telecaster back in the day after I started a family and stopped playing guitar. About 10 years ago, I started back up and play shows most every weekend. Replacing old guitars is expensive! Amps on the other hand have been replaced with technology (although it's darn hard to beat a good old tube amp)
It's a mixed bag with selling an NSX. Each time I sold one, I moved up to something better until i reached my summit (low mile, 02+ flawless NSX, supercharged). I plan to keep this one unless someone talks me out of it at the right price.
