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."
"Infiniti Performance!!!"
"My 2001 Q45t is such a beast!"
