I've had no problems purchasing parts from SpecialTAuto, and have found them to be of excellent quality. I picked up one of the 150 Amp Alternators, and installed it into my car. Everything was shipped promptly, and came with VERY detailed instructions for both installation, and operation. I had more difficulty removing the old alternator, than I did installing the new one. Common parts that you would order with certain specialty items are priced about the same if not less than other vendors, so my bulk order for the alternator, & drive belts was very cheap considering the prices paid, and the higher power alternator ordered. Over all, I do tend to buy the majority of parts from those vendors that also have service centers. But for the smaller items that you'll find, I get them thru the those vendors who mainly specialize in parts only. The replacement pulley bearings I picked up from SpecialTAuto were only $4.95 ea, when other vendors have them for about $23 ea. I also broke an antenna mast. The price for an entire unit was over $180. But since I didn't need a new unit, I was able to pick up a replacement mast from Darryl Tinnerstet @ Specialty Automotive in Washington for only $40. So, for alot of the odds & ends needed for you car, they can be had at a decent price, and you can still feel good because you can buy them from a DeLorean vendor! No matter where you go for parts, it never hurts to shop around! -Robert vin 6585 "X"
