The flagship of the Infiniti line, the Q45 sedan boasts a powerful V8 and strong acceleration, though it is too big to be agile.
The Q45 was marketed as a sporty alternative to the Lexus LS, but handling wasn't sporty, and the car lacked the spacious rear-seat and rich cabin materials found on direct competitors.
The "Q" was redesigned for 2002, when it picked up a 340-hp V8, but the ride and handling still aren't world-class.
Rear seat room is still disappointing.
At least the "Q" offers a wealth of safety equipment and high-tech gadgets, such as a navigation system and backup camera.
The Q45 was discontinued after the 2006 model year.
