What is the difference between a Dodge Grand Caravan and a Plymouth Grand Voyager?

I had a caravan and just bought a voyager. Can't tell any difference! I know Plymouth/Dodge is the same corp, so whats the big difference in vehicles?|||just little things like the look of the grille and emblems,. Nothing really. The grille is the big change.|||Hi, No offence but i think there is no difference, they are both HUGE US GAS GUZZLERS ..Regards
