  Beats everything out there... - 2003 Infiniti M45
  By bob23 - October 22 - 2:00 am

  When I read some of the "professional" naysayer reviews, I have to laugh. They obviously know nothing about real-world ownership. I shopped around, and while there are plenty of great cars out there (BMW 540, Lexus LS/GS 430, etc.), this one undercuts them in price- big time. Ive gotten so many compliments on its exterior, but when I take my friends for a ride, theyre all blown away. This car could easily cost $5K more based on performance alone. I was initially concerned about the turning radius, but its actually been just fine for me.

  NICE Car Bad Back Seat - 2003 Infiniti M45
  By logan2744 - June 21 - 5:27 pm

  Purchased the car about 8 months ago. It had 124,000 miles on it. I was on a local government auction site and saw it. I wasnt even looking for a car. I was actually looking for something else not car related. It had issues. Needed paint, starter, driver seat and some tlc. I checked for recalls and found that it had 2 recalls that needed to be done. Infiniti fixed them. While at the Infiniti Shop they saw that the gas gauge wasnt working properly. That was a $1000.00+ to repair. So after getting it painted, a new driver seat, starter and putting some tlc in it at an additional cost of $1000.00+ I finally think I have a great running car. Car has some get up to it.

  A great car - 2003 Infiniti M45
  By davidce - June 5 - 10:00 am

  I actually look for excuses to drive this car. Awesome power, unique looks, and it feels rock solid. The car gets a lot of looks. People dont know what it is. It looks like some exotic, exclusive, expensive import(which it is, except for expensive). The car really hauls. I totally dusted an Audi A6 2.7 Turbo yesterday. Just ran away from him. The guy looked really demoralized. He probably went back to the Audi dealership today to complain that his car wasnt running right. Anyway, the M45 is great. I used to have a 2000 Lincoln LS. It was a good car, but the M45 outshines it. Im very pleased with my choice.

  The car is great...ergonomics are a little off, dashboard tends to make it resemble a mimi-van. Great pick-up and nice ride.

  An unexpected purchase - 2003 Infiniti M45
  By DMZDAVE - January 11 - 2:00 am

  Went to the dealer to buy an FX45. Drove this just for comparison. The FX is still there, the M45 in our garage. Ive owned 2 Corvettes, a Roadrunner, GTO, a 442 Olds, a Trans Am and a Turbo Mazda. Only a couple were faster, but this car is unbelievable. Smooth, Quiet, comfortable, powerful all in one car. (It has surprised several Mustang GTs and an S2000 Honda owner on the freeway on-ramps.) What more could you ask for?

  The right choice - 2003 Infiniti M45
  By steve bxxxx - January 11 - 2:00 am

  Very pleased with my purchase. A dream to drive and nice not seeing one on every corning. Still a rarity on the streets. Well put together as you would expect an Infiniti to be. Traded in a 300M for better handling and got more than I could wish for in this size car.

  Understated - 2003 Infiniti M45
  By Aray - December 12 - 10:00 am

  This car is an excellent value. More bells and whistles than both my 2000 E320 and my wifes 1996 E420. Blows both of them away. When I got into my E320 after two long days of driving the M45, the Mercedes seemed frumpy and outdated - and thats a car I love. The Mercedes handles better and burns less gas. Other than that, there is no comparison - the M45 is simply better in every other category.

  Wicked Fast - 2003 Infiniti M45
  By BlackM45 - November 16 - 10:00 am

  Ive had my M45 for a week now. It is by far the fastest sedan I have driven. It will smoke a 540, E430/E500, GS430, A6 4.2 for $10K to $15K less. The look is menacing, especially in Black. The 18" wheels with the low profile tires look HUGE. The interior is first rate and very quiet.

  Quiet Power - 2003 Infiniti M45
  By Woodrow - November 4 - 2:00 am

  Its hard to stay out of the throttle in this car. Just turned 10,000 miles and so far have had only a couple of minor problems. To date I have not seen another on the road and the car definately gets alot of looks. It seems to run stronger if it is driven reasonably hard most of the time. Fuel mileage is not bad for a car of this weight and displacement. Averaging 18- 19 MPG.
