  Flash of the QT - 1998 Infiniti Q45

  Fun, smooth and powerful. Handles great for a big powerful rear drive car. 125 mph, no problem.

  Best Car ever made - 1998 Infiniti Q45
  By Eddie - June 16 - 8:10 pm

  I have had my Infiniti Q45 for 10 years. It has 190,000 miles on it and the only thing that has ever been wrong (other than standard maintenance) on it is the alternator at 135,000 miles. It is simply an amazing vehicle and is a VERY underrated vehicle. I finally bought a new Nissan this year but gave the Q45 to my 16 yr old daughter. After 4 months, I want my Q45 back! Best car Ever!

  more than meets the eye - 1998 Infiniti Q45
  By rahcc - April 14 - 2:00 am

  We stumbled across a creampuff and bought it on the spot. It had been professionally maintained and was immaculate. If you want to move into affordable luxury, test drive one of these jewels used before you buy anything new. The fit and finish are impressive - stylish without being out there - accelerates as you would expect with a 4.1 cyl 266hp V8, and rides big and comfortable. They got the "touring" part right.

  Beautiful Car - 1998 Infiniti Q45
  By LLLL - February 20 - 10:00 am

  56,000 miles, reliable, wonderful car. Superb acceleration. Though it doesnt hold resale value, its a great car to buy as it doesnt hold resale value, and a good car to keep for same reason. SUPERB dealership service! Our second Q.

  Just the Best. - 1998 Infiniti Q45
  By jim d. - December 8 - 2:00 am

  Simply the best car Ive ever owned. Told my wife yesterday that if we had a ton of money, I would just keep rebuilding this car as it aged. Comfortable, quiet, reliable, powerful, good features. Would not trade for BMW, Lexus, Mercedes,... Maybe for a Rolls?

  Terrific Luxury Ride - 1998 Infiniti Q45
  By Nicolo - March 10 - 10:00 am

  This car feels like it was built from a solid piece of steel. In my 20,000 miles, nothing has hinted at going wrong. Absolutely silent and smooth at idle, with a BMW growl when you push a little, comfortable seats and a sensible list of accessories make for the best of the 40-odd cars I have owned, especially dollar for dollar.

  The Jewel of Jewels - 1998 Infiniti Q45
  By Ed - February 10 - 3:56 pm

  I bought my Q45 10 years ago and it now has 188,000 miles on it. I am amazed at the reliability of this vehicle. It is far and away the best car Ive ever owned. It still runs perfectly- like new today. I keep waiting for something major to go wrong so I can justify trading it in but it continues to run and operate perfectly. It handles well, is very comfortable, powerful and quiet. The only item that ever failed was the alternator at 125,000 miles. I just need to tell the world that this car is the UNBELIEVABLY reliable. I am finally considering trading it in only because Ive had it for 10 years and I want something different. Im sure Ill be disappointed with its replacement. Its a 10!

  Still impressed - 1998 Infiniti Q45
  By fivelights - January 15 - 5:00 am

  Now Im up to about 175,000 miles. Check engine light is on which is emissions. Air bag light came on, which means one of the 6 airbags is malfunctioning. Other than this, my car has always been able to run without any problems. Never broke down on side of the road. Last week the dash board lit up like a Xmas tree. I sat on the car for 3 months afraid of the cost to take it it. Well I drove it to the shop and it was just the alt belt that snapped. 100 bucks. Outside of brakes rotors battery and oil change. This is the only repair that I had to make in the 5 +years of ownership. Even then I was still able to drive the car.

  I love the drive - 1998 Infiniti Q45
  By bulaboy - September 6 - 2:00 am

  This car drives nice. The wind noise is a little loud, but the drive is wonderful. I have the Q45t model, and the suspension is unbelieveable, if you can find one used, the pricing is very inexpensive.

  Awesome Car! Real Sleeper!! - 1998 Infiniti Q45
  By Steve McGee - August 5 - 10:55 pm

  Loved this car from the first time I got behind the wheel! Only paid $2500 three years ago (122K miles). Just turned over 167K....power steering pump, alternator, and two ignition coils have been the only replacements/repairs over those 45000 miles. Very sweet ride!
