Honda Odyssey / Isuzu Oasis
Today's Honda minivan follows convention: sliding rear doors and massive interior space. But when the Odyssey was introduced in 1994, it was basically a tall Accord sedan with four swing-open doors, though with three rows and a six-passenger capacity.
At the time, truck-based SUVs were all the rage, and Honda didn't have a truck. To get one, Honda traded its minivan to Isuzu in 1996, creating the best minivan bargain North American consumers have ever seen: Low-status Isuzu badged the first-generation Odyssey as the Oasis, which sold for about $2000 less than the Honda version of the same minivan. Isuzu sold the Oasis until 1999.
