For attainable, you have a few options for sedans.
The Volkswagen Arteon is actually well sculpted. It will replace the equally nice CC. Nice outside, but a rather bland interior sadly.

Chrysler 200S was not only beautiful sculpted, it was subdued, but elegant and looked far more luxurious and sporty then it's price made you believe. Also best interior you could find.

The Mazda6 is well sculpted. Nice smooth curves but sadly a slow engine. But still av ery nice design.
