Had my Sahara since Feb. of 2000. Has 85,000 miles on it. Have had to replace the differential and the axle seals (twice). Probably have spent about $2k in replacement maintenance since purchase. Biggest complaint is noise! I have both the soft and hard top, unbearable on highway with soft, mostly unbearable with hard top. Can't even have a conversation with the other passenger. Guzzles gas like an F150 at half the size! But put the top down and drive it in the mountains, heaven.
