On this week's episode of Grease the Wheels, we get into the nitty gritty when it comes to test driving customers' vehicles. Any manager who says that you should blindly test drive a vehicle before putting it up on a lift to see if it is structurally sound should listen to this episode. The aforementioned pitch can be a seriously bad idea, especially if that vehicle has serious problems. We have all seen the “just rolled into the shop” posts where a vehicle shouldn’t have even made it into the shop, and we get into some of the dangers that driving a vehicle like that can pose to both the technician and the general public.  We also get into some of the most dangerous cities in America to drive, but for most of them they really have no excuses compared to some of the other parts of the country that go through all four seasons in one afternoon. We also get a bit scientific with the idea that most people are too oblivious to know that they are bad at driving, as well as what happens with your brain when you get into an unpleasant smelling customer car.  Also Uncle Jimmy classes-up “truck nuts” and recreates classic Dukes of Hazzard stunts with his mom’s Vega.
