Around these parts, the biggest chick cars are the RSX, the Eclipse, and the Jetta... oh yes, the Jetta, the car of choice for the Long Island JAPs. And around these parts, all the cool people drive TL's 
If I buy a car next summer (which I am planning to do as long as gas is not 10 dollars a gallon), it will probably be a pretty pimped Jetta or Golf/Rabbit. I like the look of and the basic numbers of the Dodge Challenger for a relatively low-priced car. I'd want to look into that more, though.
Challenger is pretty expensive if you want a V8, and the Camaro's V6 trounces the Challengers.
What's the mileage on the Camaro? The only reason that I'm seriously considering a Challenger is because it's at the 30mpg highway mark.
If you get a Jetta look into the new turbodiesel they're offering with like 50mpg.
I'd have to worry about diesel gas coverage in my area, though, and although I haven't gone out of my way to see how many stations have diesel, I have a feeling it's not that many.
There are no mileage figures available for the Camaro yet, but it uses the same direct injection 3.6L v6 that gets 17/26 in the CTS. Are you sure the Challenger is getting 30mpg with the 3.5L? The Charger doesn't and I don't think Challenger EPA figures are out for the 3.5L. The Charger gets 17/24 with the same engine.
ALmost every station has diesel in NY, you sure?
edit: Even the Avenger only hits 30mpg with the 4cyl, v6 is 27mpg.
