1. Full-width wraparound taillights are essentially a Detroit idea, but no American car ever had as simple, straightforward, and pleasing a design solution as this.
2. The added panel for the center high-mounted stop light is neat and unobjectionable.
3. Notice how the rear fender surface flows smoothly back from the maximum width established by the bulge over the rear wheels, making a broad shoulder above and a clean highlight on the flank.
4. The steel door remains as original, but the sill projects outward a bit, with a small, tight radius at its top, which is extended into the fender bulges as a character line, elongating the body length visually.
5. The hard horizontal line established with the paint break on the sill between body color and black below wraps around the rear of the car, interrupted by the exhaust cutouts.
6. The rubber bumper buttresses are effective without being overly awkward.
