Service can be an issue. You have to find a dealer with a trained Crossfire mechanic. Parts are an issue. Plan on anything that you need not being in stock. Winter driving is not the cars strong suit. Winter tires help. A little weight in the back helps. But this is not a jeep. It is perfectly happy sitting on top of packed or heavy snow and not moving at all. I have spent 4+ years putting 40K on the clock and other than the flurry of initial TSBs, I've had no issues other than the seat heater. I would think that the concensus on this forum is that the car is very reliable. I have never heard of anyone changing a timing chain. There is the occaisional car that develops a problem that seemingly can't be fixed. These are rare and I think this relates more to the service training issue mentioned previously.

Be careful listening to what experts outside this forum tell you. The experts are on this forum. The other sources of information are just guys with opinions.
