Researching parts is a good idea but only works up to a point. When you have a business and need multiple parts every single day, how much time would it take to research every single one? That means multiple brands of multiple parts. Probably work for personal use but not really practical in business.
Fair point, might consider doing the same with overall brands instead of individual parts. When I went through my suspension couple of years ago, all the factory type parts I used brand Mevotech if I recall, instead of MOOG, based on cost and overall ratings of the various parts I needed. All came packaged and finished nicely, no problems with fit and no quality issues have arisen so far.
What I am saying is "everything is defective" is a cop out. I mean if one truly believed that they would either give up on repairing cars and buy a horse and tell your customers to do the same, or try developing their own parts line to make a fortune with parts that aren't defective out of the box.
