I got mine for the styling. there's nothing else like it on the road and there are so few of them. Is it underpowered? Depends on what you are looking for. I have had a lot of fast cars, this one is quick enough for me and I have a LTD. I can't afford the SRT and that would only get me in trouble anyway, very happy with my LTD 6 speed. NOW _ No problems at all, another Chrysler winner! I had two PT's before the Crossfire. One of the complaints I hear most is the lack of aftermarket parts. I've torn up enough cars in my 55 years, so I might get a set of wheels and a cargo cover down the road but that's it, I like it just the way it is so that's a non issue with me.
The wing automatically comes up at 63 mph or you can raise it with the push of a button. If you want a "tuner car" then pass on the Xfire. The SRT has a fixed wing. If you want something fairly unique get a Crossfire. My 19 y.o son bugs me all the time to drive it (maybe when you know what freezes over) he drives an RSX-type S so I guess it appeals to your age group. I will tell you one night I was going to the grocery store and a rather nice looking young lady was staring at my car so much she ran into the door at the store.
I guess you'd call it a flip key. You push a button and the metal key pops out.

Good luck - Pat
