Here's my dad's "VW Truck" otherwise known as the Caddy here in the states.
I was about to comment on those old rabbit trucks. We had one for quite a while and literally beat the crap out of the poor thing, it just kept going and going and going and going. Got so bad it couldn't start even in the summer unless you rolled it down a hill and poped the clutch in 1st. Sold it back to my father's friend (who we bought it from) at somewhere between 280K and 350K miles and he drove it for quite a while longer. 40HP diesel with a 4spd, front wheel drive. Who needs 4WD when you can bounce your way up the rutted muddy hill at 40MPH. Worked almost every time the first try, though the shocks eventually died from it. Could even do old "death hill" in Northern Kentucky (I71/75) at 40-45MPH on 3 cylinders. I learned to drive it when I was 10 or 11, loved that thing at the time.
I'd definitely be interested in a mid-size truck from them if they can make it a good value, dependable and usable (i.e. towing, mileage, off-road capability.) The Tourareg is ok, but doesn't have enough potential to be viable---for me---off-road wise. Definitely not easy to upgrade properly at least.
I'd also be worried that they'd try to make a US version based on the Dodge Dakota. They recently did this with their van (Routan is a Dodge Caravan rebadged) for US models.
MSG to VW engineers: If you're going to rebadge, please base it on Toyota Tacos or HiLux. Offer a solid-front axle option (upgrade) for us purists and we'll buy!
