Costs are quite high in general due to limited production and hard-to-find parts; biggest problem is definitely the Nikasil cylinder lining fiasco, don't buy one that hasn't had this addressed. It was covered by a recall in the 90s, so should have been done. The self-leveling suspension is also a big issue you want to check out, but that has nothing to do with the engine.
