I do a little bit of everything in GT5, drift, drag, circuit.
The only time I don't play everyday is if I'm on a Battlefield 3 stint. (Look up the GTP BF3 forum if your interested in that game, we have some real pros over there) and everybody here is very friendly and willing to help those that want to help themselves.
Big tip: if you have a question search the site for it before starting a new thread, odds are some has already asked and been answered the same question.
^+1 Or use google, most gt5 questions get put close to the top of the results anyways. You can add me if you like. I don't play online much if at all, but I usually have my tuned cars on share if you want to race one but can't afford it.
For tunes, instead of asking go to Adrenatune It is just about all of the tunes from everyone on this site, and I have yet to not find a car there.
tip: If you are new to gt5 as well as the forum, seasonal events are the best way to get money. If you are only new to the forum, welcome!
