May be calling it a new Chevelle is a mistake then as the nameplate carries too much baggage.
You'll have to forgive me, as a Brit, the Chevelle doesn't mean much to me and I don't think I've ever seen one in the UK (that's not to say there aren't any over here though!).
I still reckon though, that if that front end could be grafted onto the new Pontiac G8/Holden Commodore 4-door platform, it would look great. Whilst I like the G8 and it's sister cars, they are still upright saloons. I'd love to see a modern muscle saloon that a little more sleek and coupe like. Think Merc CLS low cut roofline, or even the Chrysler 300c/Dodge Magnum.
