What year did Toyota Previas start being manufactured with 5 doors?

Two doors came in with the Mk 2 Previa in 2000.

I'm looking for a second hand 8 seat toyota previa.
However I really want one with two rear passenger doors (one on each side) for ease of getting a large family in and out, during school runs etc.
I know the older models only have a rear door on the drivers side and the newer ones have rear doors on both sides.
But can anyone help me by telling me the exact year that the cars started to be made with doors on both sides?
