I bought the Kubelwagen a couple of weeks ago and like it very much. The battery is not hard to change if you are careful. You can switch between 4wd & 2wd by holding down the light button.
I also bought a very nice 1/12 scale figure of Michael Wittmann made by DID on eBay to use for a driver. He comes with a couple of different uniform choices and a lot of accessories to use.
Also got a 1/12 scale Mauser K98 for the rifle rack. Looks great!
