For me, it was the horrific array of crappy commie cars that got me ROFL, especially the part when James breaks the transmission button on the big Chaika. I've just noticed something else as well. When he's poking his finger in the hole where the button used to be (he does it two times), look carefully at the meter/indicator unit besides it: you'll see a red light half-heartedly light up in the bottom. James' action must have seriously shorted out something in that dashboard!
The whole deal makes you wonder how the cars were put together at the time. I've read long ago that the factory workers sometimes used hammers to ram in screws instead of, say, a screwdriver, in order to catch up with the workflow...
