Bought mine private party back in 2002 with 99,600 miles on it. I just hit 136k. With the exception of things I consider basic maintenance (fluid changes, new tires, new shocks), I've had next to nothing go wrong with my Jeep. It's fun to drive in bad weather, and has yet to let me down. For a 10 year old Jeep, she does what is expected, gets me where I need to go no matter what the weather. As for fuel economy, it's an SUV that is 10+ years old, I accept that.
Power heated mirrors and the 4x4 system she came with.
She's 10+ years old. I'm sure anything I would suggest was handled already.
