I Have had two separate orders this month from Rock Auto. Both arrived with amazing speed, one arrived the very next day. The parts were correct and a good value for the price range I CHOSE, in both instances. They afford you the opportunity to purchase the cheapest or to up grade to better or best parts. If you choose cheap, well, you get what you paid for sometimes but the choice is yours. I see many fault Rock for cheap parts, they don't make them they sell them and again you choose the quality of part you want. If you don't know the difference or what is best for you, then go to someone who does know the difference and pay them to get it right.
I am extremely pleased with every order I have received from them but then I read and compare before I buy and if I am not certain still, I do more research as that is my responsibility not theirs so I don't order the wrong parts.
