My friend Derek got a Mint 1998 xj update with cruise, 2" lift, ironman shocks, sway bar disco's, unmarked cloth interior, alloys, and only 136 K on the clock for $5000 in Perth. Absolute bargain and absolutely tip top cond.
Bargain.
Parts are cheap and available, and plenty of room for touring, if theres only two or three people.
Grands can be expensive when they fail, (I own two) and TJ's are a bumpy ride over corrugations, and with a soft top, youd have terrible dust and noise to deal with.
spend time searching for a good xj update i reckon, with a good fullsize aluminium bullbar, (much ligher over the front wheels) it will save the suspension from destroying itself prematurely over the corrugations, and if you hit a big roo at speed, the cars gonna be stuffed whether it has a steel or ally bar on it anyway.
Happy hunting.
