Well a lot of them have the same engines & transmissions; but if you have a lot of people you'll be driving around, you'd want the grand caravan...The only difference is the length. I would go with the standard size, it'll probably get better gas mileage and cause less wear on the transmission & engine.
The only difference between the Dodge Grand Caravan and the Dodge Grand Caravan Sport is mostly aesthetic. The side cladding on the Sport model is the same color as the body of the vehicle, the spoiler is visible, and there are other convenience items. It also has a firmer suspension than the Grand Caravan.
