New Golf R For Track Days?  

What are peoples thoughts? Im really struggling with this one.

You can flash these from home and pick up an extra 100hp keeping everything stock. They run 11.95 sec 1/4 miles with only the flash tune.

I can do a novated lease so I pay for half of it with pre tax dollars through my work. So saves me like 7k. But you are still looking at a total 55k spend after all the savings. But its new and has a warranty.

Or do I go for something someone has already modified. Like an old evo with forged internals and 400kw for 30k? And track that?

Or do I buy a new wrx sti?

Or if its a just for fun car do I go mx5 and put a supercharger on it?

What car would you pick if you had a budget of 60k for a new car or 35k for a 2nd hand car? If you wanted something that was heaps of fun and that you planned to take on track days?
