A bad choice of car, it's too new and very few dealers selling them across the UK. If you intend to keep it for a number of years, then fine, but if you intend to sell it after say 2 years, you may have trouble. It is not replacing anything, so is based on an older model, the Sebring.
You are better off buying something already established and known to the market, this may be a dud.
US spec'd cars are hard work over here, the Neon never caught on, the Voyager is well known but expensive to run and a bit long in the tooth now. The latest coupes are superb, Mustangs, Challengers and Chargers to name but a few, but running Hemi's will hit the pocket.
Me? I'd go for the Mustang and perhaps the other two
