A few Caveats, but great car

"this is an AMAZING value if you buy one used. For the price of a Sentra you can drive a 340HP "4-Door Mustang GT". Pearl white, tan leather, chrome wheels and all the bells and whistles for under $20K. I bought this one 6 months ago with only 28K miles on it. A $50K car new for $17K now. This is my 53rd car (not a typo) and probably one of my top 5 favorites to date. NO ONE knows what it is, yet it turns heads like the newest car out there. This was Infiniti's answer to the Chrysler 300 Hemi except it beat the 300M to the market by a few years. Definately ahead of its time. Do not by this car if gas mileage is a priority. Do buy this car if performance and luxury at an economy car price are a priority. Pros: power, luxury, reliability and looks Cons: there are 3 things to confirm have been fixed on the '03's (the 04's seem to be exempt) 1. fuel gauge reading higher sometimes - requires replacement of the entire cluster @ over $600. 2. some early M's had issues with piston ring seating, so check for blue smoke on start-up. stay away if it's there. 3. oil changes - confirm that the oil/filter was changed every 3 to 4K miles -- see piston ring issue above. This is critical for this car. Infiniti will run the VIN for you for free o confirm maintenance over the life of the vehicle - assuming all services were performed at an Infiniti dealer. 3. CD changer in glove box -- the '04's placed in in the dash, where it belongs Buy one, if even only for a year of fun -- someone else has already covered most of the depreciation!"

"I was first impressed by the M45 when I drove it back in July of 2003. It had conservative styling with lots of power on tap. I actually like the fact that it doesn't look sleek and sporty, so it promises little and delivers a lot in terms of performance. After owning one for a few years my only complaints are the creeky noise coming from the glove box area when driving on bumpy roads. I knew it had limited rear seat legroom when I bought it, and it hasn't been much of an issue because my kids are still young and won't be topping the 5'9" mark for a while yet. Another car I considered back in 2003 was the Mercury Marauder (with an MSRP about $7,000 less than my M45), but I'm glad I got the Infiniti. As a side note, there were so few 03 and 04 M45s sold that most people don't know what it is. I like driving a car that can't be easily classified so people can't attach a stereotype to me by what I drive."

"I've owned several feature-rich Nissan vehicles, and recently made the jump into the Infiniti category. This M45 is a beast! It boasts a powerful V8-340 HP engine, excellent features, and a plush, attractive interior. It rides high on 19" premium wheels with rims that are more attractive than most any I've seen. There is a large-screen display for temp control and audio control, which only lacks in that it does not have GPS functionality (at least mine does not). I like the fact that the 6-disc changer is easily accessible in the glove compartment, yet I am disappointed that a single-CD feed is not provided. Heads turn when you drive by, as there is no surplus of this vehicle on the road, and it has an extremely unique look to it. Overall, this car is attractive, powerful, and classy. If you're like me and you A. Are done buying new cars that lose value too quickly, B. Enjoy premium styling, handling, and features at a reasonable price, and C. Appreciate the quality from a manufacturer like Nissan, then get your hands on a well-priced used Infiniti M45. You'll be glad you did!"

"I was looking for a car, used, with unique styling, plenty of creature comforts, a great ride, rear-wheel drive, good value, and...power. The 2003 M45 has it all. Since purchasing it almost a year ago, I have put several thousand miles on...and enjoyed all of them (my wife still has not driven it, other than a few miles during a long test drive). The drawbacks, that I can easily live with, are too big a turning radius for a car of this quality, an occasional brief hesitation before the 340 horses kick in when I put the peddle down, and it really isn't a winter car (I live in Fargo, ND). I drive my 4wd SUV during the winter and look forward to dry pavement come spring and several more thousand miles in this great car. One of my favorite moments was sitting in a local coffee shop and watching a man walk around my car several times, obviously very interested, checking out this beauty."
