Obviously all used cars now and if you see one on the lot steer clear and let it rot on the lot. We have owned one now for about 4 years and up til recently have been some what satisfied. It has about 80K on it and everything is falling apart. Like previous poster gas guage is unreliable and it has been in the shop waiting for a part for over a week now. The whole instrument cluster has to be replaced!! A big rig has a tighter turning radius. Interior lights have been replaced a few times too and rarely work correctly. Infinities are not built to last.

I have owned my M45 for just over 5 years. This has been the most enjoyable, reliable car I've owned and I've had 19 cars. After 5 years, it still turns heads at the styling. Odd and unique....which is why I love it. Not a lot of them on the road. The power is second to none in its class, the features are top of the line for a 2003 model and it handles better than any BMW, Mercedes, Lexus I've had the pleasure of driving. So many reviews complain of gas mileage.....what do you expect in a V8 performance car??? It's not a Hybrid!

I bought a used 2003 M45 in 2006 with 28000 miles on it. It is black with brushed aluminum wheels. It also has hand painted silver and gray pinstripe along the length of the vehicle. This picks up the chrome and the wheels nicely. This car is a beast on the road. I have complete confidence in the capabilities when highway driving. The car is very stable. Stays flat on the road. No pitch or yaw issues for a car of this size. There is more than enough power to get you in/out of trouble ;)... The V8 is smooth and responsive. It responds with a growl during acceleration at any rpms. There is no equal for the money. What a value!

The car is great...ergonomics are a little off, dashboard tends to make it resemble a mimi-van. Great pick-up and nice ride.

This car had lots of positives, but the few negatives does sour our ownership experience. Our M45 has a very unique look, which I've come to like. The interior is still very nice. Our car still drives very well - it doesn't feel like 108K mi. The power is very impressive. The aluminum suspension components cut unsprung weight. A lot of things have broken, which is upsetting. Infiniti service writers are nice, but they will not fight for the customer. Our air bag light has been on since a hair over 50K mi. The warranty is good up to 7yr/70K, but they wouldn't fix it. The oil issue stinks. Due to the bad service, I won't buy again.
