I bought the car new and now my youngest daughter is ready to start driving. Except looking like a dad's kind of car show wants her. I have never had any issues with this car. It has been a pleasure to have for all these years. It now is worth way more to me than if I wanted to sell it or trade it in. I would own this car again and again after that. I wish that Americans would build this quality of a car.
I'm an outside sales guy in the electronics industry, I've owned many cars, Ford, Chrysler, GM. I drive my cars to the end of their repair life, meaning to a major failure usually it's the transmission. I've never had engine blow, but every American car I've owned had it's transmission fail well under 200k, most around 125k - 150k, not bad but this Infiniti continues to amaze me, no major repairs due to wear. I did replace a CV joint but only because the boot was torn probably kicked up on the road. The navigation algorithms are not so great, it's ok in a pinch, my phone is better. I would buy this car again, or the M37 with low mileage, it will just go forever!
2007 M35 base bought new in 02/2008 as a leftover. Now have 62,000 miles. Overall it has been a very satisfying, reliable and fun to drive car. Unlike others here who complain about gas mileage, I have averaged 22.8 mpg on REGULAR unleaded in mixed driving since the car had 1,000 miles on the odometer. My complaint is road noise and tires. Replaced the Goodyear RSA's at 41,000 when the noise got unbearable. Now with Cooper Zeons and another 21,000 the noise is back in spades. Likely will switch to Michelin MXVs. Only warranty issue has been replacing the 4 wooden door trims. Still have not replaced brake pads. Oil changes & filter changes only. Car uses no oil--a real driver's motor.
Uses a modified version of the platform in the 350Z and the G35 and shares some of their sporty and rough-around-the- edges "muscle-car" characteristics, while also overlapping some with German premium brands -- but without matching their finesse, quiet smoothness, and "aristocratic" style. You only get a five (not 6) speed manually shift-able automatic transmission, so highway mileage suffers; but, this car is all about fast acceleration, not about finesse or keeping mpg over 20. Inside, it has many of the upscale electronics you'd expect from Japan, yet includes a lot of the old-fashioned buttons too which I found tedious but some might like as familiar.
This car is a monster. I bought a lease turn in with 16.8 K miles, non smoker car build in 09-07. I'm not too crazy about all the electronic doo dahs but have learned to get used to them. When you step on the gas this car really moves. Many of the reviewers have said the handling improves with Michelins. I put new Michelins on her today, and wow what a difference. Great car, great value. Next car is definitely going to be an Infiniti. My last car was a Japanese made Acura and I was very satisfied with her.
