What Owners are Saying About the 1998 INFINITI Q
"Best car ever made!"
"I have owned my 1998 Infiniti Q45 for almost 12 years and it is simply the most amazing vehicle I have ever owned. The only problem I've had is the alternator went out at 125000 miles. The car handles well, has good power and runs as good as ever. It amazes me that it is so reliable. I recently bought a new Nissan and gave the Q45 to my daughter to drive. The Nissan doesn't compare. I'm thinking of a way to get my Q45 back-but she loves it now. Infiniti got it right when they built this gem. What a car!"
"Best car, so far."
"05/08. I bought my '00 Q45t in April '07, 80 k miles. Now, 110 k. I have not had one problem with the car. Oil changes and tires have been my only expense. Everything about it is outstanding. I'm going to hang on to this car, and if I find another one with low miles I'm buying it - just to have it."
"Best Car I have ever owned. And lowest maintenance"
"This car runs like a champ. Super powerful but quiet and luxurious. Stereo is Bose and its awesome. Automatic seat and steering wheel adjustment with 2 settings. Handles like a dream. What a luxury car should be. Never planned to keep this car so long but I have no reason to give it up. The newer Infiniti’s are all much smaller. This is close to or is a Full Size car. Room for 5. The paint job is amazing. Garage kept but it looks like new. Clear coat on metallic White. Beautiful leather interior, A pleasure to drive on long trips with such a smooth ride. After almost 20 years my maintenance costs other than tires, and brakes are ridiculously low. Most recently I replaced the Radiator fan. $350 installed. The old fan was still fully intact, just showing some age. So A preventative measure. And I once had to replace a couple bad Spark plug coils which were around $300 each. I know only one was bad. But that cured an intermittent misfire when idling. I get compliments on how nice the car is all the time. At it’s current Trade in value (very low) I intend to keep it forever. If I get a new car I will have this Q45 for guests."
