2006 M45 Sport

I have had this car for about two weeks now and it has been awesome! It replaces a G35 coupe and the difference in fit, finish and quality is amazing. I had two G35's and always was disappointed by the cheap and often squeaky interior. The M45 is a world apart in terms of materials and and the feel of quality. If anything, the car is faster too. There is no substitute for pure V8 power and torque! The list of technology and features on the car is a huge leap also. Especially if you love the gadgets like I do. I compared the Lexus GS and Acura RL and found the M45 to be the best choice for me. It is more of a SPORTS luxury car, but has all the features of the other two if not more.

Wife changes mind about M45 vs Q45

My husband purchased an M45 a month ago and initially I felt it was not as satisfying as our 2002 Q45 due to firmness of ride and being slightly noiser. But after driving it and having it this past month, I have changed my mind 100%. I love driving it and after lowering the tire pressure find it is not noisey at all. It is the best of the 7 Infiniti's we have owned, (all Q45's except for my G35 Couple)

Great car. As good as my BMW that I traded. Only had it for 3 weeks but I cannot find a single solitary problem. Fast, Great fun to drive, gets looks and waves and beeps. Love it. Kids love the DVD player. We do too. No backseat whining from the little ones.

Had my choices narrowed down to Audi A6 S line or the M45 Sport. Infiniti won hands down and didn't hurt being roughly $8000 cheaper with about the same equipment level. I know it doesn't have all the Audi features but the Audi doesn't have all the M45's equipment either. Truely a drivers car. The performance out of this 4000 lbs car is something you have to experience. Performance tires may pick up some noise depending on pavement otherwise as quiet as sitting in your living room. Controlled ride and appears to be screwed together pretty good.

I had a 2004 TL which I really liked. But, last weekend I test drove an M45 for fun and was immediately hooked on this vehicle. I traded in my TL and took over a demo with 8,000 km's on it. This vehicle is a true sports luxury vehicle. The power, handling and technology is out of this world. Even the geartronic is by far superior to my TL. The DVD audio system in my TL was the best I have ever heard until now.
