tech1990 and Diamond Hell you are definitely missing the point of my query, i completely understand where you are coming from as you both obviously have plenty experience in track days.
What i propose to do is buy a car, leave it in the garage for 95% of the year and take it for the odd track day every month or so. I dont want a competition car and i dont want something that is going to be modified to its limit.
What i would like is a fast, fun easily modified car. As i say i work 7 days a week so i'd have to take holiday to have a trackday never mind work on fitting turbo chargers or super chargers!
The origional thought about the R32 was the fact it can be stripped easily, an ARB, exhaust, set of coilovers etc... can be work done on nights.
Theres no way i'd buy something already modified to track standard as i dont know the cars history, i would never buy a modified car full stop! I modified my Golf from it being standard and thats what i'm now doing with the Lupo
