I recently saw an ex gas board van advertised for sale and I did a car vertical hip check on it and it came back as all wheel drive. I know a lot of these gas vans are 4wd but not all of them I don't think the guy selling them has a clue as he normally sells cars and just bought 3 vans as a one off. The van is quite far away and I don't want to waste my time viewing it if it's not a 4motion. My question is do yo think the hip check is right? or is there another way I can check?
