I'll have fun for the rest of my life because I'm not letting this one go!
See, that statement tells me your point of reference. You plan on keeping your current car, and aren't interested in new ones. But lots of people are. I buy a new car every 3-4 years for myself, and my wife gets one every 4-5 years. I like new cars, and I want something different than what I'm driving now. I really like what I have seen so far in the 2015 Challenger, and they had to do something, it was getting way too old looking. Something had to change. Subtle exterior changes, and that's a good thing, its a great looking car. Interior wise, that's what you see most of the time, and that has me sold. I really like what I've seen so far, nice refresh, up to date, looks tasteful.
As for the Charger, I'm considering that for my wifes next car. I don't like her current 2010 Malibu and we've had too many issues with it. I think Chrysler will be just fine if their quality is able to hold up. My Challenger has been rock solid, and hope that its something I can count on for my next one. But they are like Chevy and Ford, can't afford too many missteps.
