i would have to ask, WHY? why is the owner selling a 1 yr old spa that retails for 7-8k, for $3900? sounds as though there is more to the story....
if it sounds to good to be true......
i bought a new caldera in march this yr. as luck would have it i came into posession of a hot springs jetsetter, thru an estate sale, for next to nothing. it was in great shape BUT it was 4 1/2 yrs old. retail here in va is $5799. i put it in the local paper, asked 3200, and sold it with in 2 weeks for $2800. that's 1/2 price for being 4 yrs old, not 1 yr old...
if i had jac 385, and knew it sold for about 8k+, i'd ask $5500 and let some one talk me down to $4500 if need be..
it would probably be worth your while to pay a service call for a spa tech to come out and inspect it for you. better to spend $100 and make a more informed decision, BEFORE moving, wiring, filling, etc.....
