    1999 Infiniti Q45 - Touring

    At 242,000 miles, this is by far the most reliable car i have ever owned. i have never been inside the engine, its perfect mechanically. has a little almost unnoticeable "valvy" noise when you first start it, but quiets up when warm, its very comfortable seats have accommodated me on trips from here in Miami to Orlando and Los Angeles (twice). Standard wear items like brakes, batteries, tires, etc. replaced at normal wear times, had a problem warping rotors until i went aftermarket.

    2005 Infiniti Q45 - Base

    Pros: Comfort

    Cons: 5-speed transmission vs. 6 or 7 speed in others

    Advice: Try it - you'll love it.

    Extremely quiet and responsive. Premium Package adds some great features like laser guided cruise control, reclining rear seats & rear seat climate and sound system control. Best car in its class for quality, value and performance.

    2002 Infiniti Q45 - Base

    Pros: Motor performance

    Cons: Electical system

    Advice: Don't buyt

    For a luxury auto , this car is a disappontment . The sensor light on the wheel for showing 'flat ' comes on and the dealer has never been able to fix it. In addtion shortly after the 60,000 mile guarantee was up , the sturts on the trunk wore out, the ignition switch was faulty and now it needs a new starter . Further the motor for the window on the drivers side is faulty and needs repalcement . Worse , when you take the car in for repairs many of the parts are on 'back order.' After this expierience , I question the quality of any Infiniti product.

    2005 Infiniti Q45 - Base

    Pros: Computer prevents the car from pitching forward during hard braking.

    Cons: Fit could be better - occasional vibrating noise from front passenger seat area.

    Advice: I drove a 2004 Lexus LS 430 and did not buy the car because it looks frompy and there are so many on the road. It performed well but did not excite me. Try the Infinity Q45 before you by a bimmer, caddy, Lexus, or BMW. You won't be disappointed.

    Firmly planted on the road yet never a harsh drive. The car accelerates so smoothly you don't realize that you are at 70 in a few seconds. The engine is extremely quiet and wind noise is less than a Lexus according to some reviews. You are surrounded by American/Japanese-like luxury with the handling of a high end german car with Italian-like styling that does not draw attention to the owner like other high-end cars. It's in a class by itself.
