throwing my 2 cents in on this.. my 01 Ex with 40,800 miles.. (and gaining 100+ miles a day) has been 100% reliable.. the ONLY 2 things that I've had replaced have been the Firestone tires(IMHO better tires than the Goodyear Wranglers Ford put on it) and wiper blades..
there are NO squeaks, rattles etc from it anywhere, doors close with a solid thunk, it shifts from AUTO to 4x4 high to 4x4 low without complaining, brakes work very good and don't pull to either side, it accelerates better than a 4300 lb vehicle should with only 205 hp(since it has 4.10 gears from the factory)
I've taken it off roading numerous times and only once has it let me down, when I was trying to turn around in over 2 ft of snow did I get completely stuck, so bad that I couldn't get out of it without help of another vehicle.
Its hauled 2 bucks back from hunting(not too bad, considering that it's only been used for one hunting season)
the leather interior isn't cracking, the carpets are't wearing out the CD player, tape player and CD changer work like they were brand new. A/C blows cold, heater works like a champ, all the lights work and havn't had any bad bulbs.
All in all, I don't think you can get a more reliable vehicle from ANY manufacturer.. (oh yeah, this is the 4th Ford that I've owned, a 94 Ranger, 92 Taurus SHO, 97 SVT Cobra and now the 01 Explorer) and I'll DEFINITELY be buying more Fords in the future.. since ALL of them have been very reliable vehicles and the most that they've seen the shop is 3 times(for all of them combined)
