Interesting introduction! Have you tried looking here or more specifically here or, if you can't find the answer to the question you are asking, then I find looking here really helps.
Failing that, a post about GT5 might be better off in the GT5 forum 💡
You'll find you can get a long way on this site if you show a bit of initiative and do a bit of looking 👍
I heard there might even be, shock, black ones, and even white ones! If you are lucky, you MIGHT even spot a yellow one (I know, calm down...the excitement is too much!).
I know this thread has been locked, but I have to add: There is a reason why new members are not allowed to start threads in the GT5 forum. Here it is.
