I don't know what they would delete off the looks of it so that informed people know it is not an SRT-4. I think it would be cool for the SE,SXT, R/T to look good to. Not everyone wants a turbo I guess.
They will probably have a more aggressive body trim option for the SXTs and R/Ts, but I doubt there will be a SRT design package only because the Neon's SRT design package didn't sell as well as they hoped (so I'm told.)
I think if they offered it not in just the last year of the Neon it would have sold more. That should have been the new face of the Neon in 2003 when they had the little face lift. Then added the "nostrils" and hood/ bodykit/wing for the SRT one IMO. I think they then would have sold more and not tried to push it as an extra package in the last year of production, which many knew I think.
Currently there are no plans for any additional appearance package for the 2007 Dodge Caliber. For the inaugural year, appearance packages are uncommon since they take some time to design, test and produce.
I expect the assortment of factory options and Mopar accessories to grow quickly when the Caliber is established in the marketplace.
that would probably be the rallye: [i "painted" the cf headlights/tails & hood, got rid of the bottom paint that was on it, put on some black spoked wheels, and stealth-ified the bottom fogs & "intercooler" [which is actually a radiator]
i think a simple set of conservative side skirts, and front & rear lip would go a long way. Since the stock wheels on the r/t are a pretty good size anyways, a nice 1"-1.5" drop would complete the look IMO.
