I saw the one at the Detroit Auto Show. My sister-in-law fell in love with it. She drives a PT Cruiser right now. She's excited to drive the kids around in it. But she probably won't get a srt.
The one thing that I saw on it that was a cool feature was the extra storage place above the glove box. It looked like another glove box that lifted open from the top of the dash. It turned out to be a cooled space to put your cold drinks in, and they would be kept cold for so long as you wanted. I would use something like that.
I definitely wouldn't look at the Caliber to replace the XF. They aren't in the same class!! I think the Neon people are going to hate it too. It's too much like a station wagon. Or a mini-me SUV!
