ive had r33 gtr and fq340 and still come back to cossies.
They are nice and fun for the first week but then i get so bored, they are more expensive to take to the next level that a cossie and dont get the looks.
I just didnt get the same feeling either. I mean they are better cars with better handling etc etc but they lose more money are harder to sell and as i say they just didnt give me the same feeling.
Keep the 3 door mate, you would be mad and really regret it if you didnt.
