The Porsche 911 has the same rear-seat issues-a near-complete lack thereof-that the 6-Series faces, and its cabin is a bit colder and more clinical, but its sheer performance and handling are superb, especially as you climb the ranks toward the Turbo.
Practicality is also a 911 boon, with front and rear cargo compartments due to the engine location.
Mercedes-Benz's SL eschews the 2+2 layout for a pure two-seat configuration and a roadster-only body style, but has even more weight and invasive technology issues than the BMW.
Nevertheless, it's a composed, capable roadster, and the folding hardtop adds versatility.
The Jaguar XKR offers classic styling and excellent on-road dynamics, being the closest to a traditional sports car of this group aside from the 911.
It's also eminently luxurious.
