I love Rodeos. I like Troopers even better cause they have more room and you can fit a 3rd seat for 2 more people....
And yes the Rodeo and Passport are identicle.
Also the Trooper and Acura "Something or Other" are also Identicle.
If it were me I would try to get the loan without a cosigner. It would force you to be responsible and besides that I would have a hard time co-signing for anyone else. (my opinion)
If the banks wont let you get it without someone to co-sign then ask them.
BTW - Rodeo starters are SO hard to get in and out! Took me quite a while!
