Wouldn't hold your breath on finding heated rears at the JY. Bit of a rare bird - never seen any myself.
XC is a decent ride. Have what you just got since new. Bit of a love/hate kinda car. Maintenance is a bear, but once you work out ALL of the kinks, it's much nicer. On top of the usual high mileage white block maintenance, after 150k mi, expect to need a new/salvage tranny, some ignition key stuff, fuel pump relay, bevel gear reseal or rebuild, driveshaft rebuild, likely some AC recharge, and a head rebuild.
On the plus side, the thing performs fantastic when you hit a turkey and going 80. Most it did was peck out my fog light lense
