I've never really understood people stripping and selling interior for cars that are getting rarer and rarer... because it'll be a total ball ache trying to replace them if/when the time comes that they realise the small weight saving wasn't really worth it (unless their car is dedicated track toy) and they want some sort of comfort back.
Stripping something like a Saxo out isnt an issue, their interiors are shite and worth about 40quid... and the lightening will have an effect on power to weight of those cars since they're struggling to make massive power as it is. But on something thats big power, does it really make much difference?! Specially as most of the time people fling in a cage when stripped out.
Cheers,
