1999 Infiniti Q45 Reviews

Bought this car new in Sept 1999. Just love it. It has great power and a nice quiet and smooth ride. Love the auto adjusting seats and steering wheel with two separate settings. The Bose Audio system is amazing. The paint has held up so nice it looks like new. The only issue I ever have had was an intermittent misfire when idling. Replaced the Spark plug coils and it is now perfect...
this is a great car for the mileage. nonsmoker, taken great care of the car.
