That's funny - I was thinking the exact same thing the other day (ELR). But then I realized, unlike the Volt platform it's built on, the Caddy isn't a liftback, even though the roofline kind of suggests it SHOULD be:
No hatch kind of kills the idea for me.
Seems from what I've read about that car is GM over-engineered the drivetrain - ownership/reliability surveys back that up. Issues seem to be around things like infotainment. I could kinda maybe see myself rolling the dice on a used Volt.
