rite running costs, well ur prob get aboot 25 miles to gallon if its a 110 (which I would HIGHLY recommend!!)
other costs, put aside a couple grand a year for repairs, UJ's clutches, ball joints, propshafts, timing belts, radiators, all seem to love needing replacing.
unlike many other vehicles, milage dont mean jack!its all aboot the chasis, bulkhead, crossmember condition-NO RUST NO HOLES NO PATCHED UP HOLES IS WAT U WANT!
umm wat else, ah make sure high low diff lock on/off all engage with little more than a sturdy push (they can b pretty stiff). gearbox, test in all gears at different revs.
i would recommend a 200tdi or better a 300tdi engine, they are more refined than earlier engines and not overly complex with electricity like the latter td5 (landyzone regulars HATE electricity in their landys)
hope that helps a wee bit, theres some real jerks, oops I mean experts on here that'l be of some real good help for ya mate. the likes of slob, redhand, odenne, and even yella are the people to head for for advice, technical stuff and a rite good **** take!
enjoy,
TEDDY
