thanx for the replies!

jonathan.... no way and i riding 100+ miles on a folding bike! lol! we both have top fo the line carbon fiber.... as cool as the folding bikes are.... i don't think they can compare in comfort (or efficiency) of our current road bikes! and of course... for mountain biking no way! lol!

jeff.... hmmmmmm hubby won't be happy with having the practically dismantle the whole bike... at least i don't think he will! that's one of his major complaints with our MDX.... he has to remove his seat cuz his bike it too tall with it on! but i'll mention that to him!

the main reason we were thinking roof rather than trunk is for that TEENY TINY bit more security... being UP on the car rather than off the back.... i mean i truly do prefer them to be inside.... especially after some idiot tried to steal mine... and i'm sure he had NO clue exactly what it was he was trying to steal! propably thought it was just another bike! UGH!

katie.... we'll probably look at the prius tomorrow.... i just can't imagine you can get two road bikes much less two mountain bikes in one???? but i could be wrong (we have issues with the handle bars of the mountain bikes JUST fitting in the MDx! he was looking at the 2008 escape online last night...

i just started thinking aboutt he drag and what it will do to the MPG... of course.... i can't imagine it would be as bad as the MDX (about 17ish overall)

i guess we need to do a lot more thinking and a lot more researching! we may just be better off keeping the MDX????????????????????????
