I will be looking at a local 07 AT Sahara Unlimited today. The jeep looks completely stock, one owner with 107k. The mileage worried me a bit, until I researched somewhat. The guy says the miles are all highway with his commute being 100 miles a day. Just wanted to get more opinions on the mileage. What should I look for when test driving? What would be a good price? I originally wanted a manual, but if I can get this for a good deal, I may bite. This will be my first jeep.. Thanks in advance.
