One of my least-viewed chops of all time, lol, the Mazda RX-8 notchback. I'm not sure why this hasn't been more popular, I love it, but I think it could be the fact that the RX-8 just wasn't very popular. I shortened the wheelbase and took away those Saturn-like rear half doors. This would be a 2-seater with a parcel shelf behind the front seats for packages. The car could be lighter and tighter than the regular hatchback 4-seater and I think could have provided additional sales. Generally I like the profile of notchbacks more than fastbacks, but give me a moment and I'll find a hundred fastbacks I love!
