You can't tell whether that Mitsu is coming or going without a doubletake.
This thread has really got me thinking; maybe we're doing it wrong. Rather than trying to add kammbacks and boat tails, perhaps we should be starting with a reasonably aerodynamic minivan and chopping the back so it can be sloped back. Of course, most vans start with engines that are way too large because they want power for cargo, but design-wise, it might be the place to start. Or maybe a Scion Xb?
Imagine cutting from behind the front door and tapering it back to a boattail.
Starting with a smaller, reasonably good mileage vehicle and chopping it off behind the front door.
I don't do photoshop, but use your imagination.
