I have a 92 Trooper and swear by it too!
I drive ALOT, on my job, about 40,000 miles a year. I put 250,000 plus miles on my Trooper in 6 years and had 3 problems with it.
1. Cassette player died, Radio replaced under warrenty
2. Lost a wheel bearing, around 180,000 miles
3. Fuel pump died around 210,000 miles (I figured at the time it pumped over 12,000 gallons before going south)
and other than consumables (tires/batteries/light bulbs, etc) that's it!
Now I drive a Company vehicle, better deal for me finiacally, to go this route. (Mini-van though [:X*] )
Trooper is in the garage, still drive it. Still looks good, most people think I'm full of it, when I tell them how many miles are on it, until they check the odometer.
Are they the Best looking SUV available, NO
Are they the slickest SUV available, NO
But I'll put my Trooper up against any SUV for reliablity/toughness out there (Humvee's excepted)
Would I buy another/recommend one, most definetly!
