We have a 2007 Dodge Grand Caravan with a VMI conversion. The van 'kneels' and has a power operated side door & in-floor ramp. Front seats are removeable. (They are really easy to remove, I got the passenger seat out and into the house on my own.)
My husband drives up the ramp in his power chair and because the chair has very good turning radius he turns right into the passenger seat area. There are just the two of us so it was really important that he could sit up front next to me and have a good view ahead.
It is low to the ground so I don't know how it will be in the ice and snow. But city driving on clear roads is great.
Only disadvantage to the side entry is that you need space for the ramp to extend and to get the wheelchair clear of the ramp. But so far it has not been a problem for us. Love that van!
