What's The Worst German Car Ever Made?

In honor of Germany's world cup victory over Argentina, we decided here at Jalopnik to compile a list of the worst German cars ever made. My nomination goes to the craptacular Opel Vectra.

The Vectra (in Vauxhall form) was ripped apart comprehensively by Jeremy Clarkson on Top Gear back in 1996. He likened it to reviewing a microwave oven. Ouch.

There wasn't anything specifically wrong with the Vectra, but it was offensively boring and that qualifies it as one of the worst German cars. Especially considering it came from the nation that gave us great cars like the Porsche 911, BMW M5, and the Mercedes S-Class.

Surely there are some other terrible ones, so what do you think is the worst german car ever made?
