Fun to drive luxury

Vehicle: 2003 Infiniti Q45 Luxury 4dr Sedan (4.5L 8cyl 5A)

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

Good stuff cheap

Vehicle: 2003 Infiniti Q45 Luxury 4dr Sedan (4.5L 8cyl 5A)

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.

Vehicle: 2003 Infiniti Q45 Luxury 4dr Sedan (4.5L 8cyl 5A)

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.

5th q & the best

Vehicle: 2003 Infiniti Q45 Luxury 4dr Sedan (4.5L 8cyl 5A)

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




Solid car

Vehicle: 2003 Infiniti Q45 Luxury 4dr Sedan (4.5L 8cyl 5A)

My Q-45 is one solid, reliable car. In 16000 mostly city miles I have averaged 17.8MPG. Those miles I have driven with outstanding performance and fantastic comfort. This is my 3rd Infinity Q-45 and the number of repairs required for them is ZERO. In comparison, my friends S class has had numerous electrical problems, my family's Lexus' several small problems and my BMW Z-3 a disaster. The car does not have the dingleberries of more expensive cars but, as a car, is superior IMHO
