Do not buy the Nitro at this time. I bought a 2007 and have had transmission problems that started about a month after I got it. I've taken it in for flash computer upgrades, but it still has a bucking problem. I did some research and found that this is not an isolated case. It seems that corporate really doesn't know what to do. They keep sending you back to reprogram the computer to make you feel better for a while, but it doesn't fix the problem. I have owned a Chevy and a Ford before this and have never had these problems. I would say to anyone looking at the Nitro... get something else or wait until they get this transmission problem taken care of.
