2008 Mercedes-Benz C-Class C300 Luxury 4dr Sedan (3.0L 6cyl 7A)
This is the all-round best car I found in this category. There are faster ones, but with terrible ride quality. There are fancier ones, but without any soul. There are edgier designs, but I'll leave those for the kids. This is just a friendly, highly competent, extremely comfortable, and great looking car that will age gracefully, like a Benz should.
