though, I think most would require a new shell !.
Imagine Lotus doing the same for the M100, you could maybe specify it having brakes that worked, a hood that didn't leak like a sieve, a fuel tank
that didn't split, a dashboard that didn't have gaps you could drive a bus through, a rear window you could see through, panel gaps that were consistent
side to side, gear cables that were fit for purpose, seats that were ergonomic and pretty ,and a clutch cable that was removable without dismantling half the car, did I miss anything?
Off course Honda have been doing this with the early NSX for a while now, cant imagine those needing much replaced or modified seeing as it was / is
the epitome of vehicular perfection
