Just a suggestion, but possibly under Best Buy Parts forum you could create a more specific PARTS REVIEWS and VENDOR REVIEWS.
I know that when I finally find a GTP that I buy, I will want to know what different brands/products work well on our cars and also some good reliable vendors to order from.
Ex. There are so many different kinds of exhausts - It would be beneficial if members would post their product, where bought from, price, and maybe picture/video/sound clip of it.
Just a suggestion... but I think it would benefit a lot of newbs who are just getting into modding their GP's
