since I'm one of the minority that really like the Cadillac ULC concept (except that they cut off its butt)
here's a quick-but-heavy "tweak"
...of course!, my XLC wouldn't be based on the Aveo or Spark or any existing Fwd compact
& ideally it'd have a tiny trunklid + hatch instead of being a pure hatch
but that was beyond my patience to attempt chopping.
((John, if you see this, hope you like the fin-lets))
