My favorite bit of that episode 
I liked the “Berlin to Warsaw on one tank” commercial better.
I don’t have a problem with unbiased market research to determine what the public may want but do have a problem with biased research marketing or marketing designed to promote a good or service that anyone could see is utter garbage.
The 2 VW marketing people on Top Gear will never ever, in a thousand years, admit that diesl VW is an anemic garden slug. They continued to ignore reality and slather more lipstick on the same old pig.
My favorite bit was the suicide depiction but that Berlin to Warsaw crack had me rolling!
The latter one took a second or two to soak in at first.
Speaking of great minds and marketing…
