Junky cars get dissed, then fixed. Iffy for teens.
Parents need to know that despite its relatively mature content, this series targets kids and teens, many of whom aren't even old enough to get a driver's license. There are some definite role model issues here that you might want to discuss (the host actively makes fun of people's property). And there's also the issue of the expectations that the show raises -- implying that additions such as DVD players, high-end sound systems, flat screen TVs, speakers, 20-inch rims, and video game systems are necessary if you want a cool ride.
