An S2 can be picked up for no more than a decent saph cossie, impreza or early evo.
I paid £3800 for mine:
All I have done is lowered it, changed the wheels and put in a chip which has taken it to 280bhp
Its got zero rust or rot, and can be parked anywhere without getting the attention or theft risk than the cars I mentioned above.
It is also cheaper to insure
