aaah.
i wasn't keen on firbe. otherwise i'd just make tuscans.
as for market, i was gonna aim at boyracers, young professionals. hell niche market, but if you have 'arrangements'(*) with motor industry supplies and a low-cost way of fabbing the plastic pieces you'd be in.
(*) lol - i just put months and months of grovelling back breaking ass mastering work into one word.
