If you'll check most etailers and product manufacturer's sites you'll also find lots of good info on car care. Most of them of coure will recommend using their products, but still you'll likely pick up a hint or trick on one site that can be used with any product. The big difference between other site info and Autopia is that they are trying to sell you products without the vast experiece with it's use compared to other products. At least here someone has most likely already tried every prpoduct on the market and they will give you an honest opinion as to how it works for them.
