It all depends on what you want it for.
Do you have kids?
Do you plan on loading it up to go camping?
How tough are the tracks that you want to do?
How easy is it to modify if you are going to modify it?
Do you want gas or diesel?
Are you fussed about how it looks?
Is fuel consumption important?
Are you buying new or second hand?
If second hand what year are you looking at?
There are a lot of things to consider.
It's horses for courses, but just keep asking questions, or come out for some trips and see what people do with there different rigs. I have just bought something to take out into the mud and play with and it took me months to work out what I wanted, and then another month to find the one I wanted. Cripes - one day later and I wouldn't have had it ready for O'Tooles
Cheers,
