I thought I'd add a little info to this thread.
I'm currently searching for my next 300c. I saw an '06 Hemi today that had 182,000 on it! I thought to myself... "self, you need to drive this thing to see how it has held up under those miles."
So I did. This is my report:
The driver seat showed wear from entry/exit, the ashtray drawer had to be finessed in order to stay shut, the interior door panels had some warping on the upper panel right below the windows. The Driver seat power buttons were in poor condition, but still worked. The rest of the interior looked good, not worn and no rattles. (Surprise)
For having 182,000 miles the car drove as I remember my '06 driving when I sold it (only had 40k miles on it). No noticeable lag in the tranny or engine. Very smooth, and yes...still fast.
The car did have aftermarket 22" wheels. They needed balancing and the rotors felt like they needed to be turned.
Not a perfect car, but I was very impressed for the mileage.
It felt like it would go another 100k.
Hope this is helpful.
