Dude... do you even have your own car? Do you have a job to pay for any of the stuff you keep asking questions about? I mean, if you just want to learn about things, that's fine, but posting four or five threads in a row asking similar questions is asinine. And you've posted so many questions like this before, it's making me wonder what the deal is?
I'm not trying to be a prick, just very confused as to what you're looking to do.
