I think a large part of it is the RTA... it's a shame it's so easy to make money off people by defecting them. If you've poured thousands into a car, then it's hard to justify just letting it stay defected, or wrecking it...
It must be that time of year, I have been lusting after alfa 105's... man I want something with twin webbers again... and a wood steering wheel and a funny looking dash hehehe
