I don't know how long Jim's warranty is, but I've had my Salks for a couple years and they are just fine. Since you are local, if you check the condition and they have been cared for and are intact, they should provide you many years of great music reproduction.
Mine have been moved halfway cross the country a few times, my dog has knocked them over once or twice, and besides a few little knicks, they perform marvelously. Jim makes good stuff, and people buy used all the time, so I wouldn't worry about it. Unless you order used HT3's off Audiogon and FedEx drops them off the truck and crushes them (like they did mine).
