Why it's obnoxious: Cars and trucks are cool, but they come with the unfortunate side effect of greenhouse gas emissions. Smoke stacks are usually paired with engines that have been tuned to run as dirty as possible.

Purchased by: Men with mustaches who deny global climate change not just because they don't understand the science, but because they don't like it when those fancy scientists tell them what to do.

Money wasted: $150-$300
