Wow - that's a heck of a deal, if everything's coachier and it's never overheated. I wouldn't think to sale mine for $2k even with being 9yrs/155k miles old.
Maybe $4k, but not $2k.
Hope nothing's fishy about that rig

, but it doesn't sound like you're interested in keeping it anyway. But, FWIW - if it's running good and is maintained well, it will be a good vehicle.
I personally have seen owners who have lowered their rodeo's, the newer one's as well as older. I haven't the foggiest clue how they've done it, but I've seen at least 3 within a 100 mile radius of where I live.
Only thing is, you just don't want to take them down too low; but heck, I've even seen some 1 ton dually trucks that are lowered, and if they can be lowered I don't see why a Rodeo can't.
Just ship me your 4x4 system will you??
