Q:
A: The long lived Porsche 911 series has four seats, though it's always been a 2-door, and the back seats are not well suited to full sized adults.. usually called a 2+2 configuration. There have historically been other four-seaters (928, 944), but it's the 911 and the Cayenne (SUV). However, they are planning a new four-door coupe for 2009, dubbed the Panamera, and officially the successor to the 928.
