1998 Infiniti Q45 Reviews

I had this car in storage for over 5 years. I finally uncovered it and started driving it. It is a very smooth ride and had many well-designed comfort features rarely found in many cars. I especially love the dual sunroof with a flip top portion near the rear of the sunroof. Seat warmers are nice too.
