it's something we all consider at some point
most dedicated racecars with road rego are not nice to drive around in, high diff ratios and lack of sound deadening, exhaust noise, rattles, etc etc. nor really useful in any way, the back being dominated by cage and perhaps nets to keep the helmets in, the boot housing the spare tyre (mounted specifically for quick release) and fuel system, so there's no room for your shopping either!
as much as i would have loved to get that serious with my ke25, and i would have one day, it was nice in the meantime to be able to drive around and have carpet and a stereo and little comfort stuff. and carry carloads of drunk people from parties to the pub and what not. and root on the back seat :lmao:
