so many ideas...
Assuming it's 266k miles w/o any accident/collision history and it's running well w/o any major cosmetic issues... I *think* it probably went for low-teens ($11k-13k) at the most!
This NSX would be a great candidate for (3) scenarios...
(i.) IF maint'/service is up to date, wear-n-tear items & age-related parts have been addressed (along w/ being a clean-title w/o any accident/collision history)... a great acquisition for an enthusiast for mid-teens ($13k-$16k) who just wants to drive & experience an NSX and/or track it
(ii.) IF there are any engine/transmission issues... a great candidate for engine-build for a stroker-kit or F.I.
(iii.) If there was an accident/collision in the past and/or the frame isn't 'straight' or engine/transmission have issues... a viable electric-car project: sell off the engine/clutch, intake-box/throttle-body, exhaust-system, gas-tank, ECU, radiator/cooling-system, alternator/battery-trays, TCS, and other misc' parts. Then swap in an electric motor & gearbox-adapter and load-up the trunk/engine-compartment/hood w/ batteries!
