Edmunds' Expert Review

Fast, luxurious and priced thousands of dollars less than most peers, the Q is a solid buy for comfort seekers on a budget. But if owning the best is what matters to you, drive the competition first.

2004 Highlights

The Q's five-speed automatic transmission gets a revised manual-shift mode, and the rearview backup camera now comes standard.

Its only been a month now,but i have been waiting to purchase this car since its start.I am an Infiniti lover,and most of all a Q45 lover. Since i'm a car enthusiast,of course i knew all there was to know about the car,so no surprises here.It is however,the best car for ME to date,out of 23 previous cars, all types of makes and models. Pure Pleasure...nuff said!!!!
A well kept secret

This 4 door sedan is an absolute sleeper in terms of its performance. To say it's fast is an understatement. It has really top performing set of wheels, superior to my Mustang GT and Corvette Sting Ray. The construction attention to detail is superb and the body fit up is flawless. Handling is superior to any other car I have driven. This is really a well kept secret if you're looking for a great looking, well built luxury ride that performs like a genuine high performance number.
Infiniti Q45

Terrific car but focuses too much on back seat comfort-reclining and heated back seats. Would have preferred power folding side mirrors, power seat belt height adjuster, power front headrests adjuster and passenger side lumbar support instead. Too little leg room in the rear compartment when the seats are reclined. Quiet interior until pavement breaks send noise into the cabin--the car's performance tires make more noise. Suggest swapping with quieter tires. Rides smoothly and handles extremely well on the straight and corners. High quality inside and out. Recommend over Lexus and German imports and is a better value.
2004 Q4 - Dislike the ICC
AZScott, 2/12/2010
Love the car, hate the Intelligent Cruise. Every time you pass a semi or medium to large truck the car slams on the brakes. At 75-85 mph or more, not fun. Nav system is poor, in the middle of a 20 yr old freeway it just goes awol and shows you driving in the middle of the desert. Passenger seat has no lumbar support. Purchased a used $10K Mercury Montego for my mom that has a much superior touch screen nav and passenger seat lumbar. It's generally fun to drive and quiet, but I'm not as impressed as I hoped I'd be with it.
