I drive a tractor that cost right around $150K. In the first month the engine cooked itself to death in about 15 seconds before I could safely pull off the roadway. Needed a brand new $25,000 dollar engine with less then 10K on the clock! Next the turbo a few months later, which was the original bolted onto the new engine. Peterbilt had to eat it. Has a wicked pair of airhorns though.
