2006 Acura RL 3.5 4dr Sedan AWD w/Navi System (3.5L 6cyl 5A)
This is simply a fine, fine automobile. Wonderful ride, incredibly quiet, plenty of power when needed. Exceptional build quality. Went from a 2004 Acura TL to the RL and, contrary to what most "professional" reviewers say, that is a huge step up. The SH AWD is quite noticeable when rounding curves at speed. The car just wants to go where you point it - no hint of understeer. Nav & sound systems are excellent. There's another upside to the RL - you don't see yourself coming and going all the time.
Navigation, sound system, voice recognition, SH AWD, quietness, comfort, power, uniqueness on the road, interior quality and design. Best of all - price to value ratio, especially now that the '07s are coming without navigation.
