Great stereo system, powerful V8 engine, blazing headlamps.

Uninspiring front-end looks, fussy controls.

2003 Infiniti Q45 Luxury 4dr Sedan (4.5L 8cyl 5A)
Review
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
Favorite Features
Sophisticated luxury. High tech features from voice activation to adaptive cruise control and lots more.
Suggested Improvements
Transmission and suspension both need a better sport mode - especially the transmission which needs a G35 like programming.

Review
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 doesn't 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.
Favorite Features
GPS, dash layout, 340 bhp engine, ride comfort, and all the technology this car has.
Suggested Improvements
AWD
After 3 years, I still love my Q

Review
I've always wanted a real luxury car, and I finally got what I wanted. I had to wait until March of the following model year, but I bought it new. I have never had one issue with the car since we bought it 3 years ago, so I couldn't be happier. We intend to keep this car from 10 to 20 years, so we hope our good fortune continues.
Favorite Features
Beautiful interior, lots of power, excellent handling at speed and very quiet.
Suggested Improvements
Easier to use dashboard controls.

Review
This is my 5TH Q, they've all been great cars but this one is incredible. I have the premium model with every option available & I truly love to drive it. We drive to hilton head twice a year & I won't let my wife share the driving even tho it's about a 13 hour trip. I usually have the car svc'd at key infiniti of hilton head & they can't seem to do enough to keep me happy. Forget the s-benz or the 740 bimmer, buy a Q, you'll fall in love
