The Dodge wins the trunk competition. I had a '73 Mustang which was the last year for the 'big' Gen 1 Mustangs. I took a friend grocery shopping and as we stood there with an overflowing cart contemplating the trunk she said "This isn't the sort of car a guy interested in a woman with kids drives." She was right.
After the shrunken piece of crap that was the Mustang II came out I switched to a Camaro. The Gen 2 Camaros were still real cars. When the Gen 3 hatchbacks came out I went with the Firebird. The Firebirds had popup headlights and was the most aerodynamic model GM produced to that point. It claimed a Cd of .31 which is still pretty good.
