Forgot to add, at this stage of it's life (low trade & resale value of a '96 vehicle) there is no difference between the Honda Passport and Isuzu Rodeo, they ARE in fact the same vehicle, and it's built by Isuzu.
Just make sure the Isuzu Rodeo has the 3.2L sohc V6, that same exact engine is in the Passport. Isuzu also offered the 2.2L 4-cylinder Rodeo's, whereas the Honda Passport didn't, so just make sure they're the same engine before you decide on one.
Honda, at the time, didn't have an SUV of their own, so they bought rights from Isuzu and rebadged them to be a Passport. The engine is 100% Isuzu, there are no Honda parts in it, and the auto tranny (in both the Rodeo/Passport) is a GM transmission.
The only difference at the time when it was new, would have been for resale value and length of warranty. Honda had the better resale value, whereas Isuzu had the longer bumper to bumper warranty.
