The act of fixing a car by basically pointing it in a direction and driving it as far as possible in one sitting. This is meant to stretch the legs of the car, and honestly if something is going to break it's going to be during a 500 mile road trip.
My check engine light came on so I decided to give it a Colorado Tune up and drove it 500 miles straight and it went off.

My car was in a bad way so I gave it a Colorado tune up and ended up stranded on the side on I-70.
