If your after an every day runner. I would go for a standard 4x4 (roughly 220 BHP). Ive just picked up a mint one for £4500, one owner from new, full service history Etc. For that kind of money you can pick up a really good standard one. If your after more mods you'll have to pay a bit more to get a good one. Just take your time in looking for one.

Always look for rust in the wheel arches, but to be honest most of them will have some rust.
Also look for smoke, on start up from cold and when reving, blue or white smoke isnt good.

And always get a HPI Check.
