ute = carrying big crap, no where secure to store stuff (shopping, sports gear, dead bodies), no more than 1 passenger so very impractical (unless grandma or mother in law likes fresh air), and is heavier and less aerodynamic so uses more fuel. looks good though.
sedan = cant carry anything large, plenty of space to store stuff securely, carries more people, is lighter and more aerodynamic. looks crap though.
wagon = can carry big crap (fold down rear seats are awesome), even more space to store stuff securely, carries people & stuff in any combo you want, is no longer in length than the sedan (like 5mm in it... common misconception that they are huge- they arent), and looks sexier than the lot of them!
Sportwagon best of both worlds.... most versatile of all shapes, and done right looks anything but a shopping trolley.
Btw- chicks in utes doesnt look right... sorry, dont mean to be sexist. It looks like 'she's driving hubby's car'. Unless you are actually a country chick and need to carry lots of hay or something, chicks in utes is one step from RM Williams and ball breaker. You wanted honest right?
