In the past on another car forum there was a product review forum which was organized into different categories from performance mods to care and maintenance products. I found reading the reviews and experiences of others who have bought products quite helpful in making decisions on which parts or products were worth trying out. Quite often the descriptions of products on vendor sites are insufficient and often biased. A product review section could help everyone in the community to avoid crappy products without searching and spending hours reading through hundreds of irrelevant posts.
