My choice:
Long Wheelbase mini [US]: 2002 Honda Odyssey EX
The best Minivan out there, Honda reliability, Honda durability, most powerful & refined engine in its class, the safest, and the only drawback is you'll have to wait in line to get one.
Short Wheelbase mini [US]: 2002 Mazda MPV ES Gotta live the power windows on the sliding doors, one of Consumer Reports best pick mini, updated engine, zoom-zoom with 7-seats.
Old mini: 1998 Mazda MPV ES 4WD
The real SUV wannabe and thats good! I agree with MAZkid for this.
Traditional mini (w/ sliding doors) [EU]: Volkswagen Caravelle/Multivan 2.8 V6(Eurovan in US)
The original European minivan, camper-ready, vault-like tough.
Wagon-like mini (w/ 4 conventional doors) [EU]: Renault Grand Espace 3.0 V6 24V
Europes bestselling mini, F1 optional.
