Buick Riviera concept based on the 2014 Lacrosse. Sort of a sportier version of the Lacrosse integrating features from the Riviera and 8th-gen LeSabre (the stylistic successor to the last-gen Riviera) such as the wheel wells, the dollar grin grille/lights, and overall rounded oval shape. The lights are sort of gypped from a Cruze, though squished vertically and projector-ized, and it has gratuitous rear-window kink leaving room for a Buick emblem in the C-pillar. The hood is a dual-level affair that meets the greenhouse at a point above the belt-line, much like the 1st and 2nd-gen CTS.
I'm going to be making a nice colored vector of this later today while waiting to recover a corrupt partition on my dad's computer.
