Cars for Triangles

Hey r/polyamory, I have been having a problem. A big problem. When I started dating my boyfriends, it took me less than a month to destroy one's truck by pouring in motor oil while it was running!

The thing is, that truck was really great at one thing: carrying three passengers in the front seat. I have a car of my own, but there's a problem: two bucket seats up front, and the back is basically soundproofed from the front. This leads to a lot of awkwardness, and I can't be alone in this!

Does anyone here have any recommendations for big, comfy vehicles with space for 3 up front? How do you sort out who rides shotgun?

Any insight is appreciated!
