The US drama is about a high school science teacher with cancer who turns to drug manufacturing to shore up his family's finances before his eventual demise.
It's a great show, but the automotive casting director must have been looking for ugly. Living in Australia, I'm not familiar with a lot of American cars as only a few are actually sold here. Until Breaking Bad, my ugliest car experience was the Ssangyong Stavic from a few years ago. The cars in Breaking Bad make the Stavic look almost pretty.
Walt's Pontiac Aztek is truly hideous, especially in that beige.
The Winnebago was almost equally lacking in asthetic beauty, matched only by Walt's legs in the pic below.
