From those two, I would get the CSL too!!!

the sound of that car is intoxicating, its lighter, more fun track car, and depreciation has already hit the csl, while the GTR will kill you, when its time for re-selling it....

Also the CSL, will mantain even better its value, I've been searching for second hand cars, with considerably kms, and they're price isnt cheap at ALL!!!! , its a collection car !!!!

the thing is.....you have to be very carefull what CSL you buy, ...

Also those alcantara backet seats, looks amazing, it reminds me of the carrera gt seats....all that carbon fiber in the cockpit...

Its a car I would have in mind, doesnt matter if I was looking for a two or four seater!!!

good luck !
