depends ,if you need a Trackday/weekend race car ,buy a 996 gt3 mk1 : less price ,funny and you can spend a lot of money to tune it . (380 hp are easy to have) ...but ,if want the last trakday Porsche ,in you want to "win"aganist all the other trackday cars due more power ,best setup ,ect ...buy a 997 gt3 (or Rs) .
.................and tune it !
