Never going to happen, but let's pretend we live in fairly land...................

• A real sound system.
• An option for a larger non-compressed V6 or V8.
• Some better color choices: our yellow, silver and SSB colors are too nouveau riche for me. (If you don't get it, let me say it this way: Those colors inspire a big yawn at best and a vomiting episode at worst. They do fit the personality of Celine Dion, the model used in the ads, which brings me to my fourth bullet.)
• A marketing campaign that was not written by some out of touch moron (perhaps they were not out of touch, perhaps they intended to ruin the car's chances).

Of course, if they did bring it back, I'd never own one, for the same reason that I owned and loved three Ford Rangers and would never buy the new one: They ruined the Ranger and they'd ruin the Crossfire.
Such vehicles are a one-time occurance in the industry; today's market and political climate prevent such vehicles from being built again.
