2003 INFINITI M45 Reviews, Pricing & Specs

Its a one of a kind car and the 1st M45. The body style was only available for year 03 & 04 and many feel it was the best looking. The car is sexy and a wolf in sheeps clothing with a 345 ho V8 and smith shifting 5 sod transmission. Although its a midsize luxury sedan it handles great and is deceptively quick on the low end and surprisingly fast on the high end. These are a great value if you can find one with low miles, if taken care of the will run well past 200K miles. Jan 08, 2021

performs great in acceleration - braking abut handling is a bit bellow what i expected - cornering and turn radius not up to par build is awesome but there are a few issues i could do with out like faulty gage cluster and drivers seat slides appearance is sleek and unique for todays cars cost of ownership = gas mileage sucks but u gotta pay to play - maintenance is not as bad as a Merc or Beamer fun factors = is kicks as - its a nice sleeper and hella fun to driveJun 02, 2011

I just turned in my 39 month lease of an M45. I had driven it over 90,000 miles. With 340 horse on tap, this thing took off from a stop like a rocket. Unfortunately, it then floated along the highway. While the driver and passenger found themselves in the lap of luxury, the back seat passengers had a tight fit. Handling was not impressive. This car was advertised by Infiniti as the 'muscle car' of luxury cars. It just didn't have enough 'sport' in it to warrant that type of praise. This was my first automatic transmission car and I couldn't stand it. The manumatic was a joke and never allowed for aggressive driving. I also had a noticeable acceleration lag on the highway when I went to pass. I brought this up to the dealer several times and was always told that it was normal. Driving the G35 when my M45 was in service showed me that the gearing had to be the issue. The G35's transmission responded immediately to either my manumatic gear selection or just the pressure of my right foot. My overall impression was that the M45 was a beautiful car to look at and it is still rare to see them on the road, but the lack of any real driver involvement had me wishing I had made a different choice 39 months ago.Mar 28, 2007
