Jeep Gets a Six-Speed – the NSG370 Manual Transmission

The Jeep brand is one of the iconic names in automotive history. Created as a personnel carrier for the military during World War II, the brand has been owned by several manufacturers over the years and is now part of Chrysler Corp.

Some Critters Have No Respect for the Law

In my opinion, the new Dodge Charger is one sweet ride; turn it into a police cruiser and it looks fast and intimidating just sittin’ on the side of the road. When our local sheriff dropped off his patrol car, it still looked impressive; however, the service-engine lamp and supplemental-restraint lamps were both illuminated, and there was a noticeable seat-of-the-pants misfire.
