Oh look, a Toyota with an automatic. How innovative.

The shapes and proportions play a large part in that... Considering it's been 50 years now for the mustang, it's doing pretty well.

The 64 Mustang had a 108" WB, overall Length of 181.6" with a 68.2" Width and stood 51.2" High.

Since I haven't seen anyone mention Magnum 500s in the approved posts yet.
