I just bought a 2005 Liberty Sport with 67,000 miles for $6400. Carfax was clean and appears to have all the necessary recalls done. I bought this so I can sell my '97 Wrangler. We just had a baby so the extra set of doors was a must. What are some MUST things I should consider or take a look at as a new owner? With the new baby, my priorities right now are gas mileage and safety.
