  • Best car Ive ever owned!!!!!!!!!!!!! - 2003 Infiniti M45
    By -

    If you are looking at cars in the $35,000 or higher price range you MUST drive this car before making a purchase. I leased mine from Infiniti of Kirkland and my payment is less than most cars in the $35000 range. What a deal! Driving this car is like driving a hand- made, top of the line Bentley. And the 340hp V-8 is truly magnificent. Dont cheat yourself by paying more for a BMW of Lexus....drive this car first.

  • Refinement Needed - 2003 Infiniti M45
    By -

    Well the ergonomics could be better. The shifter, cup holder and armrest need to be reconfigured. So does the CD player (single in-dash is preferred). I have 3,500 miles on the car and I had a problem with the Trans. getting stuck in 2nd. gear @1,200 miles. Tried everything, finally shut the engine off and restarted, appears ok. The dealer tested it repeatitally with nothing found (the trans. is lazy while in automatic mode, when stepping on the gas to down-shift and pass). Oh the gas milage does stink, and I dont drive it wildly, ok very seldom... getting about 18mpg.

  • One major flaw a buyer should know about - 2003 Infiniti M45
    By -

    The only major flaw about this car is the gauge cluster. If you run out of gas with the needle on a quarter tank that is what it is, not the fuel pump. Test drive this model and try to drive it down to at least the quarter tank. If it dies the dealer is either to fix it or lower the price. Nissan speaks for itself. It even has a low rumble RRRR. The tires are 18/low profile so expect to pay more. People shouldnt compare this to a sports car because its on the same lines as a GS. I owned a 97 Camaro SS. Fast but its a luxury sport. Classy car. People will tell you I have heard of a M but never actually seen one. Very smooth design.

  • Value - 2003 Infiniti M45
    By -

    My brother has owned a G and two Qs and has had great luck with all of them. He took both the Qs to 150K with very little trouble. So I bought the M knowing it had the same great engine of the Q. A great used car value. I picked up an M for 32K and love it. Outer style is okay, but what a superstar to drive. Center console controls are fine once you get to know them. You get great fit-finish, power- handling AND reliability. Typically you dont get all of those benefits in one package. Drive one, youll see. The 06 model looks much nicer, but wont be nearly as soft. If by chance they do get as soft, Ill buy one when this one is worn out.

  • Super M45 - 2003 Infiniti M45
    By -

    Buying experience at Prestige Infiniti (Las Vegas)was by far the best and I have bought quite a few cars. The deal was awesome (great lease terms through IFS), first class customer treatment, and the M45 was the finest I have driven for the money.

  • Bad Black 45 - 2003 Infiniti M45
    By -

    The M45 is an excellent value; it compares favorably with many much higher priced vehicles. The drive train is very strong and extremely smooth. I get 22-23 mpg highway in very high speed driving.The vehicle has great brakes and great acceleration and handling. The seating is very comfortable with great adjustments.The spoiler adds greatly to the appearance.

  • M45: Great Machine - 2003 Infiniti M45
    By -

    This is a great automobile! The body style is unique and sharp. Although similar lines to the new Cadillac, I find the M45 lines much more refined compared to the "boxy" look of the Cadillac. The interior is very handsome looking. The automatic retracting seat and lifting steering wheel for ease of entrance and exit is a nice touch. The tiptronic 5 speed transmission lets me enjoy additional acceleration and control when I want to have extra "fun". The audio controls on the steering wheel make audio operation safe and easy while in motion. The voice controlled audio and climate control system also make for ease and safety of control while driving.

  • Always liked the style and power. - 2003 Infiniti M45
    By -

    I just purchased a 2003 M45 with 70,000 miles on it. Ive always liked the style and the power is great. Its a great used car bargain Im just glad I never bought it new. The quality is below luxury in my book. I also have a Lexus the quality of the material and finish is top notch. The Infiniti not so much trunk struts dont work, center arm rest is cheap and feels loose, sunroof liner coming apart, fuel guage not reading correctly (recalled ), engine doesnt start up on first try sometimes, and airbag light is on. Alot of issues for a car with 70k, but Ive always wanted one and I dont regret buying it for $7500. Especially since its not a daily driver. I have a Gs300 and Yaris for that.
