got talking with a buddy last night about the old citation X-11... could you do a basic, boxy little hatchback in that vein... something with a little flair but not too over the top? a sporty chevette/citation sorta thing... like a tougher aveo, i suppose, but with the overall citation profile. a little rear wheel drive hatch would make a fun entry-level car, if a little impractical. kinda of chev's response to scion... more of a butchers knife versus scalpel sorta thing.
that's all i can think of! no tiny 4-cylinder either... but at the same time no V8. assume it'd be an affordable car... a small V6 would be cool, i think.
