2003 INFINITI Q45 Review
Price Range: Not Available

Edmunds' Expert Review
by the Edmunds Experts
Pros
- Great stereo system, powerful V8 engine, blazing headlamps.
Cons
- Uninspiring front-end looks, fussy controls.
What’s new
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.
Edmunds says
Designed to compete with the best sedans on the market, the Infiniti Q45 bundles prodigious levels of luxury and performance into a reasonably priced and attractive package.

Bullet Proof Reliability - Incredible Performance

2003 INFINITI Q45 Premium 4dr Sedan (4.5L 8cyl 5A)
What we want in a car is a little like the work we what from our car mechanic, i.e. - Fast & Cheap & Good.
The trouble is... you only get to pick two because the holy trinity of all three is as elusive as a Powerball Jackpot.
So what most of us look for in a car is a balance between the car world's current holy trinity of Performance & Reliability & Fuel Economy.
I believe that this is … exactly what F50 Q owners have done.
These cars are unbelievably well put together and their
performance (esp. if the car is equipped with the Sport package) is enough to make most full sized BMW owners wish weren't so pretentious.
Fuel Economy is the bit that lags at about 17/22 but what a car!!
AMAZING VEHICLE!

Best Kept Secret Ever

2003 INFINITI Q45 Premium 4dr Sedan (4.5L 8cyl 5A)
I purchased my preowned (one-owner) 2003 Luxury Edition this past August, and got it for peanuts (the sticker on this car when new was $62,750). This is my 3rd Q45. After driving my 1997 Touring edition for over 168,000 miles with no major repairs needed, I was looking for a newer replacement. At the price I paid, I could not pass this car by even though it is 8 years old. This car is … amazing and I still can't believe it did not do better from a sales perspective. I've owned Mercedes, BMW's, Acura, & Lexus and none of those cars can match the features, ride, performance and fantastic reliability. In case you can't tell, I love this car.

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.
