I bought this car for the luxury, performance and reliability. I love it except...all the maple moldings on the inside of the doors had to be replaced (turned out to be bad glue). Infiniti had no problem replacing them. At 65K miles the front left wheel bearing went. Haven't ever had that happen on any other car. At 80K miles the transmission went - not in any forward gear, but in reverse? I generally keep my cars for 150K miles and I've never had transmission problems or even had to change a clutch. Needless to say, I'm disappointed.
The M35 of this 2008 - 2010 generation is one of the most solid cars I have ever owned (Yes, I've owned, Mercedes, BMW, Audi, Lincoln and Cadillac, among others). Only downside to this car is that it's a bit thirsty. Over many, miles we've been averaging 19-20 MPG. However, this is probably the last series that still runs on REGULAR gas....and runs well.
I've had car for just over 2 years. I'm toying with the idea of trading it for the convertible G37, but I can't! Every time I drive it, the high quality interior, the quick acceleration, the sharp handling, the easy-to-use controls and the OUTSTANDING sound system featuring the music box (no more CDs!,) tell me that this is the car for me. I'm 6'5" so comfort is important to me. I always feel comfortable, even after driving 2-3 hours straight. Gas mileage could be a bit better, but it's not a deal breaker. Just a great overall sports sedan.
I've owned this vehicle for 6 months and felt it was appropriate to write a review. The drive is like a sports car feel in a family vehicle. Response is quick and braking is very good too! The only slight disappointment is road noise but that is expected considering the performance handling assets. Overall, the car is unbelievably quick and the Bose sound system is one of the best I've ever seen in a luxury vehicle. We've only put 10K miles and dependability seems to be there. Dealing with the dealer on maintenance issues has been pleasant but not cheap. I would recommend this vehicle for one whose tired of the basic economic family car, tired of the SUV mode, and the best value.
For what would otherwise be an under-powered luxury sports sedan that is an excellent value, the steering issue called tramlining makes the M35X an unsafe highway car. Everything else is wonderful: comfort, electronics, etc.
