its ok really for me as my car is a track car only, it used to be a road and track car but the price to run it was way to high.
but even as it is now it costs a lot to do i only ever get about 3 or 4 track days out of the OMP disks and brake pads
3 track days out of the tires if i am lucky.
1 track day out of the oil IE engine oil and gear box etc etc.
and then you have to fix any damage from mistakes.
but the biggest killer for any track enthusiast is the quest for more performance, its like a bug 1 or 2 track days and you already find you have reached the capabilities of the standard gear so then come a hole new worry for you bank balance.
so far to develop my fiesta its took about £3,000 to 4,000 but that includes the 2 litre engine from a 1.6, fully adjustable coilovers, uprated brake pads disks and calipers and braided lines, 4 paddle clutch, uprated tires and semi bolt in roll cage, and there is so much more.
but you are a braver man than me as if i crash mine on track its only going to cost me £300 for a new shell, somhow i think it would be a lot more expensive to replace that BMW
