Bought it in Reno, Nevada and drove it up to Alaska 2 weeks ago. Awesome vehicle with a smooth ride, smooth transmission, strong but quiet engine, and pretty good gas mileage! Will keep it for a long time! JH
i wish I could drive this thing straight into a tree! can,t stand it. I've put so many new parts into it and still can't get it to run right..... lesson learned "never buy anything from a person named cleatus!"
