I was in this position a couple of months ago needing a 4WD car to make the trip to Tiverton for the F3's worthwhile, so we bought a secondhand XX4 worlds on eBay. Having never driven anything else 4WD I can't comment on how good they are, but I have never found any car as easy to drive as the XX4. However they are stupid money at the moment because alot of people seen to agree that they're a great car which keeps prices quite high...
