I own a 2007 Jeep Liberty Sport 2wd 6spd manual with 14000 miles. I am wanting to upgrade to 4wd, as I have never owned a 2wd jeep, and will really need 4wd when the snow hits. I have been looking around for a while and I found a deal that I think is pretty good. Its a 2006 sport 4wd with 29000 miles. The upgrade will cost me $2000. Would you do it?
