If you are looking for an extended warranty on the '99 or '00, your best bet is to find one of those cars at a Mazda dealer's used lot that has been certified by Mazda. If it has been certified, you will get the remainder of the factory warranty (36mos/50k) plus an additional 12mos/12k on top of that. Also, I believe you can purchase additional Mazda coverage. See http://www.mazdausa.com and click on Pre-Owned and then Mazda Certified Warranty. It gives a list of everything that's covered which is just about everything. It even states specifically "Lysholm Compressor" so you know for sure that that's covered.
