A nice conceit with shutlines is to try to unite them inside a larger frame.
The 1998 Mitsubishi Colt (or Mirage) is not otherwise a very interesting vehicle. However, students of design might like to look again at the tail gate treatment. The lamps, screen and metal panel are enclosed inside one line which can be traced from the top of the rear glass all the way around to the bottom of the liftgate and back. It could have been done in a nicer fashion though.
There is a small strip of metal under the edge of the lift gate which could have been eliminated by bringing the edge of the tailgate downto meet the top of the rear bumper. They would have avoided that unsightly weld line shown in the detail. The Ford concept manages this (see below). The Colt’s lamps would not have had the same final shape since a lower edge would have probably resulted in a simple horizontal line.
Here’s how Ford did it in 1996:
