In my line of work I go to many automotive parts manufactures facilities. From foundries in Mexico, all through out the U.S. and even have a die casting customer that I visit in Nova Scotia that produces servos for the 4l80E. You name it and I have probably seen it made, engine blocks, crankshafts, headlight assemblys, you name it. Alot of the parts used on todays cars are produced not by the auto manufacturer but by a subcontractor. One example (of many) is GKN Sintered Metals (a very fine company I might add). They have a plant in Sanford NC and a state of the art facility in Celya Mexico. They produce CV joints for just about every type of vehicle, from cars to atvs. Now me being a gear head I always keep my eyes peeled when I'm in places like this and do my own personal quality evaluation of the parts being made. But most importantly I always ask who their strictest customers are and it is ALWAYS Toyota first and Honda a close second. I don't think that I have to list who the least concerned customers are. Please understand that I don't have a perticular love for imports but I have yet to personaly see any Toyota or Honda parts made in mexico. I can't say that for the big three or even several german car companys. Every car company is going to have recalls but some do try harder to produce a quality automoble.
