There is a number of cars throughout history that seem so strange or bizarre that I honestly cant believe they reached production – let alone what they were thinking when they designed them. There is a few exceptions, but virtually all of them came from GM. Lets take a look at these unusual cars and appreciate the risk and brazenness that had to take place for these cars to hit the assembling lines.
Recently at a Cafe, a young couple sitting next to me were taking about turbos (what are the odds!). Thinking that this conversation was right up my alley, I got talking with them and they asked me a question that caught me off guard: why are there no naturally aspirated diesel engines?

I stumbled upon a number of cheap brands and most of those had really bad reputations. But then I found these MuchoMacho tires under the brand Cosmo.

But there is a problem with this; the treadwear rating number, also known as UTQG (Uniform Tire Quality Grading) is arbitrary and means absolutely nothing.
