I am in the market for a used TJ and I came across a '97 Sahara with a 4 inch lift, 33s, and 228,500 miles for $7,900. It looks and drives great, but I am concerned about the very high mileage... Mechanic said it needs a new rear diff, but aside from that it is very solid for age and mileage. I am thinking about offering $5-6k for it. The jeep would be my daily driver and used for light wheeling while I am in school. What do y'all think about buying a TJ with this many miles? Is it worth it? Thank you very much.
