M.P.
Take your car seat base with you and try it. It's my guess that you can because cars have that capability now. But I've not seen a minivan that has 3 bucket seats in the second row.
My daughter and I both have 7 seat mini vans. Her second row has 2 bucket seats and they both allow them to plug in their car seat base.
Hmmm. I answered here but wondered why a duplicate of a question you asked yesterday?
