The rodeo is an excellent vehicle in my opinion....tremendous bang for your buck.
Some people doubt the Rodeo's reliability, but my parents both drive Isuzu's, and have had no problems whatsoever. Its a tough and rigid car, with alot of room, that can easily traverse some pretty rugged terrain with its on the fly 4WD. The city ride is kinda rough, due to what it was designed for, so you may want to make a note of that. Overall....for its price...I'd say you can't beat it.
I don't know if they still do this, but both of the Rodeo's we purchased we also got a factory rebate on that saved us alot of money....I suggest you look into that and see if they are still doing this offer.
