My dad gave me a jeep as my first car with 210,000 miles on it. it was in awesome shape, garaged all the time and was good on gas, got about 25 miles to the gallon. the straight six was not short on power and still ran great at 215000 miles. Only new parts on it are; oil pump, U-joints tie rod ends and ball joints, everything else is stock. Jeeps best vehicle ever i think they really designed this very well.
The interior, plenty of room with comfortable leather seats and power everything.
I love it the way it is I don't think it needs any improvements.
