I know it costs a little more but I do factory parts. if you like the way it is from the factory, don't change it is my opinion.
I love factory parts, but I think if you know the OEM suppliers you can save a few bucks.
really depends on what you are looking for.... certain things are better are different stores... so really all that matters is what are you looking for... then look around for the best price
Best price for competitive parts is a no brain-er, but in the past from my knowledge is to avoid any electronics and sensor that are made in China, for instant CAM, MAF sensors, headlights tail lights and ETC..
I can't help but noticed the price difference from one supplier to the next, for example doorman vs ACdelco, Dayco vs Gates etc..
Too bad some web stores don't say where they are made because this to me will make a difference in picking which supplier to buy. I would rather buy things that are made in the USA, Canada then Mexico, but no way would I buy China, they are mostly junks.
