Don't let the current political environment dictate what you pay for gas. CNG or gasoline. Of the dual fuel cavaliers this is the best one. The 2003 and 2004 multi-port fuel injection CNG is the only one to buy. Has just as much power on natural gas as gasoline. 4 speed transmission this one is a rare find with the comfort options power windows power door locks power mirrors. Air conditioning is cold. Tires are good. Has a full set of on rims one season use studded snow tires. I have owned a lot of these cavaliers and my sons have worked at powder mountain in the winter going out and around full out stuck Jeeps with four wheel studded snow tires. It's a great option for people who know what car they want.
