Outer Limits 4x4 Board

i've got the opportunity to buy a 2006 NP GLS on gas that has only done about 25,000km. they're asking $28,000 which i think is a pretty good deal (deceased estate).
i've never had a car on gas before and wondering if anyone has got any advice on the 3.8 and it being on gas, problems to look out for, economy and just the np GLS in general
cheers

depends upon what sort of gas system,

if its sequential vapour or liquid injection , its good, if its the older mixer type, no good, will only have problems later on.
