Well Belbo your in trouble now...
I own a 2001 TJ and have had no major problems with her.
I have had one sensor go out and my warrenty paid for them to come out and pick her up with an over night stay at the stealership.
I am a plush type of person here and am highly ignored by these brutish, rugged type of Jeepsters you know the type no A/C...who cares about the heat, windows, floor mats.. kinda like that Tug guy who wrote ya.
Got ya Tug
Yes Air Conditioning is a must! Say yes to an Automatic transmission as well. The TJ series is a smooth riding beast that will get you up and down the mountain with little to no problems.
As with any type of vehicles you will find lemons out there, if your looking for a used one take a careful look at the frame and suspention for abuse.
If your looking for a new one then a hard top is a must (ski racks are the cheapest for the hard tops).
But be aware...once you buy one you will regret it! Owning a jeep is a diffrent way in life. It's not an SUV... its an Jeep, the original off-road vehicle.
Your fellow jeep owners will wave at you ( please explain to wife early on or get a real good lawer here).
A little lift here...bigger tires.. eww fender flares... a winch... the list goes on and on and on...( Jeep= Just empty every pocket)
Just ask any one here we already know!
But not buying one! you will kick yourself every day for not buying one.
My TJ makes the trip up to Park City and Brighton Ski resorts twice a month and it always looks good sitting in the parking lot.
