Of course, 'chokes' don't exist any more on cars. The computer works out the required fuel-mix from the sensors' data, and via the fuel injectors, adjusts the air/fuel ratio and the advance/retard accordingly. The only difference from the old way of mixture-control, is when it goes wrong: $1500 for a new Engine Management Computer vs. $1.99 for a bit of bowden cable and a clothes peg. Anyone remember that trick?
The 'cardboard' body was actually quite a good idea. It's a resin composite using cellulose wood fibers; it's light and won't rust, and they gotalotta trees in East Germany! Downside is in a slight bump, you're driving a naked shopping-cart. But, nobody laughs today about modern flimsy plastic fenders/bumpers which collapse if you hit a wasp at speed, now do they?
