  The Only One - 2003 Infiniti M45
  By cosmicm - April 11 - 10:00 am

  If you want quality, luxury, performance -- without owning the same car as every other joe on the highway - - this is a simple choice. Infiniti of Cincinnati is offering them for as little as $399 on a 39 month lease -- and nothing out there can touch that. Almost everyone that sees my car loves it (Graphite on Graphite with chromes). Most people think it is a Mercedes or Bentley. If you are at all considering a BMW 5- Series, Lexus G Series, Audi A6 or Mercedes -- you owe yourself an M45 test drive.

  Dont buy it. - 2003 Infiniti M45

  Obviously all used cars now and if you see one on the lot steer clear and let it rot on the lot. We have owned one now for about 4 years and up til recently have been some what satisfied. It has about 80K on it and everything is falling apart. Like previous poster gas guage is unreliable and it has been in the shop waiting for a part for over a week now. The whole instrument cluster has to be replaced!! A big rig has a tighter turning radius. Interior lights have been replaced a few times too and rarely work correctly. Infinities are not built to last.

  THE VEHICLE IS FUN TO DRIVE. THERE IS NO WIND NOISE, IT CORNERS WELL. I HAVE NOT HAD TO HAVE ANY REPAIRS MADE TO THIS DATE. I WOULD LIKE FOR IT TO HAVE MORE REAR LEG ROOM. ALSO THE TRANSMISSION SHOULD SHIFT MORE POSITIVLEY.

  The Bomb!! - 2003 Infiniti M45
  By Scott - January 11 - 11:03 am

  I have owned my M45 for just over 5 years. This has been the most enjoyable, reliable car Ive owned and Ive had 19 cars. After 5 years, it still turns heads at the styling. Odd and unique....which is why I love it. Not a lot of them on the road. The power is second to none in its class, the features are top of the line for a 2003 model and it handles better than any BMW, Mercedes, Lexus Ive had the pleasure of driving. So many reviews complain of gas mileage.....what do you expect in a V8 performance car??? Its not a Hybrid!

  really poor handling in the snow. traction control doesnt help and is even a hinderence. otherwise a ball to drive. A very well kept secret as I have only seen two others on the road in three months.
