Got bored and drew a profile of my car, then erased the C-pillar and made it into a wagon of sorts. Not half bad, honestly. Looks like it would have been GMs answer to the Taurus wagon, but a bit more luxurious. Would this have sold? I highly doubt it, but I enjoy imagining in my head what it would look like in real life.
Drawn on a ThinkPad X200t using Autodesk Sketchbook Pro, which I suck at using.
