God people miss the point. It's ok that they copied the British Leyland-episode from TGUK, but parts of it just ended up beeing pointless and stupid.
Filling the American junk cars with water was just dumb! Kids probably think its funny, but for adults it had no value at all. I bet I lost you already so let me explain:
The test in TGUK did two things:
A) Test how well built the car was. If water rushed out quickly it had pretty bad panel gaps, door seals and so forth.
B) Test the suspension and power of the car. More power and better suspension mean that they could travel further before the water dropped below the steering wheel.
The point of the TGUS water-test was:
A) Look silly on TV. Mission Accomplished!
Seems like Americans like TGUS more when they feature old crap American cars. People rave about the Fiero and the Roadmaster and I can't even begin to grasp why, they are pretty bad at any standard.
Anyways, if you compare TGUS to Top Gear Russia, blunt force trauma and AIDS, I guess it isn't that bad. But compared to Top Gear UK it just falls flat on its face and it's a shame it ends up so bad when they have many years of experience to build on.
