Lol... David, I knew there was something more I liked about you!
In HS, I was painting my 68 Bird, and often borrowed my Dad's 78 GMC Sprint (El Camino) I often gave a group of girls a ride home and while they fit fairly comfortably in the bird, it was a tight squeeze in the Sprint. (6 girls and myself driving... all INSIDE the vehicle, none in the back) Not to say "I" was not very comfortable... but it was a tight squeeze! BUT, in the bird, we also ran out of seat belts, but they did all fit in the car a little better... still a tight squeeze...
Yeah, for cruising the family around, I think they will fit in the bird right now (only two kids) but I'd better get the GTO as a back up I think...
