Could we please stop listing the x2010 in any "fastest cars" discussion.It will win a short drag,long drag,0-60,0-100,0-150,0-200,0-300,200-0,100-0 and everything else in between.Lets just exclude the x2010 when comparing cars.Its obviously the fastest in every category.
So why ask which car is the fastest? Seems most people should already know by now.
Would be smarter to ask which non race car is the fastest or which car is second fastest or some other such thing. The bottom line is that if you ask the question "Which car in GT5 is the fastest?" Any answer other than X1 would be false.
