The sill is rather too high for one's arm to rest comfortably on the sill for any length of time -- if you adjust the driver's seat high enough that this becomes (marginally) possible, your forward visibility is chopped off by the windshield's header panel and your forward-rightward view of street signs, businesses you might be looking for and pedestrians about to behave stupidly is blocked by the rearview mirror.
Not really, just a not-very-thoughtfully-designed car.
The usual rearward-visibility problem exists due to the trendy wedge shape with the deck lid plane way up in the air. Those oddly-shaped rear door windows don't hinder outward vision nearly as much as they look like they would.
As mentioned previously, about the same as my '92 LeBaron sedan (Spirit-Acclaim type car) for any given road surface. Maybe a tetch quieter. Not much wind noise, but plenty of road noise. And on this 1700-mile-new, still-got-its-paper-temporary-licence-plate example, there's a front suspension rattle that reminds me of when the sway bar bushings would go away on my '92.
Finest precision German DaimlerChrysler blah blah bullpoo.
