The Germans were about technology. When they Built their tanks. When they started using Prisoners to build them, there were many, many instances of poor quality work, or intentionally shoddy work, intended for the Tanks to break down after a few miles. - - - Updated - - - At one time, years ago, I had a 1950 Cadillac M-42 "Duster". It had a Cadillac engine, an open turret housing dual 40MM Cannon for Antiaircraft, as well as ground targets. She was a beast, used gas like no one's business. When I got it, it had been arsenal rebuilt and had less than 100 hours on it, since that rebuild. I also had access to and driven a Czech OT-810 APC. It was built Post WWI by the Czech's using production equipment captured from the German's who had used it to produce the Sdkfz. 251 series. The OT 810 used a totally different engine and there were other differences as well. The Re-enactment group I was part of bought and imported it, and converted it to look more like the 251. I had a LOT of fun driving and maintaining these two vehicles.
