Well here is my point of view
I had a limited budget and I knew I wanted different rims/wheels on my NSX and I wanted to put in an Exhaust and intake.
so when I was looking I did check the prices of the car in relation to how much those mods cost
so my NSX I just purchased worked out like this to me
'92 NSX Silver (worth more than red/black/white)
1. Comptech Exhaust ($1200)
2. Comptech Sway Bar ($200)
3. Aftermarket SSr Wheels ($2500)
so I figured If I purchased the one I got it would of cost me $3.7K more to mod it
so I had a choice of 2 cars.
1. '92 NSX BONE STOCK with 35K miles
2. '92 NSX all listed above with 68K miles
(They both had the Snap ring fixed and new clutch)
so I got the higher milaged one since it was cheaper for me
so to me they kind of add value to the car.
