Overview & Reviews

The Q45 enters into 2003 with a few changes. Refinements include a higher numerical final drive ratio for better acceleration, slightly revised front and rear styling, new exterior colors, the addition of standard heated seats and a full-size spare tire. An optional satellite radio is now being offered along with some new optional equipment packages.

• Great stereo system, powerful V8 engine, blazing headlamps.

• Uninspiring front-end looks, fussy controls.

  Fun Car - 2003 Infiniti Q45
  By adwls - March 28 - 2:00 am

  Phenomenal performance goes along with high fuel consumption. Level of comfort, and quality of interior first rate. Infiniti service second to none. Last three cars were Cadillac STS

  Just Outstanding - 2003 Infiniti Q45
  By phil baatz - July 23 - 10:00 am

  I owned the car for 2 years and I never had such an enjoyable automobile. The service department at Infiniti has been just outstanding, it has been a better experience then Lexus. Cannot say enough good things about the car. Find one used and it will be the best buy you ever had in car ownership.

  The New - 2003 Infiniti Q45
  By Young CEO - February 25 - 2:00 am

  Just picked up the 2003 two weeks ago. The car is gorgeous and a dream on the road. This is my first Infinite after driving an Acura Legend (another great car....Acura should have never discontinued)and before that I drove a Toyota Supra. The Q45 is by far the most technically advanced vehicle Ive ever owned. The voice recognition is very convenient. The Bose sound system is crystal clear.I compared the new BMW "7 series", the Lexus and the Acura RL. The Q45 beat them all hands down and all of the electronic features are user friendly and actually work, unlike the 745i. Give the "Q" a test drive and see for yourself.

  Good Stuff Cheap - 2003 Infiniti Q45
  By seldomseen - November 17 - 3:43 pm

  I just bought an 03 Q45 in pristine condition. The luxury options on this car are more than generous. The power of the engine is amazing too. It doesnt seem to handle as taut as the 03/04 M45s but it does drive a lot smoother though. This generation Q45 is attractive and comparably equipped as the likes other Asian and Euro vehicles within this "new" price segment.

  Fun to Drive Luxury - 2003 Infiniti Q45
  By W.Kahrs - October 25 - 1:43 am

  Best valued luxury car ever. Dealer support is excellent. Have achieved 21 MPG on commutes after learning what works, but expect 17 if you like to experience the 340 hp. This car never fails to impress passengers who comment on the excellent ride. Loves to run at higher speeds
