I drive a Prius plug in (same size as standard Prius) and we are expecting twins! It's leased and I'd love To upgrade to a highlander but wondering if we can possibly fit 2 rear facing car seats in back comfortably. Problem is that I'm 5'10" and DH is 6'6"! He has a huge 4 door truck but I think I'm gonna need a bigger car now too and not sure how I'm going to afford it! And boy will I miss my carpool access sticker! And the gas savings! ! 😁
