Drives and handles very well on the road.
Drives and handles very well on the road. The only surprise was during purchase. I expected it to have a Bose sound system like my G35 had, and the automatic front seat and steering column. On my G35 these two systems moved in unison and had memory for the position of the seat and steering column that could be set for two different drivers. The only other thing is the absence of a spare tire. Those run flat tires ride very hard and are not cost effective for owners.

Donna was very helpful.
Donna was very helpful. She showed me a van that I was interested in. And then I decided I wanted to see a second one and she went out and found it for me. She is very knowledgeable about the vehicles I wanted to know about and suggested she could help me in the future because I did not find anything yet.
The car is great everything about it but the
The car is great everything about it but the entertainment system is garbage. It’s costing me over 3 grand to replace it. It just stop working. And from doing my research the company knows that this a PROBLEM. And theirs no help for me as a customer. I love my car but 3 grand for a radio is ridiculous. Infiniti should replace all radio systems for free or have some type of copay.

The internet manager and staff did a wonderful job in setting up appointments, finding the right car and communicating.
Great Car.
Owned this Q50 for a couple of years. It handles well and gets me the looks that I like. I keep my cars impeccably clean so that I get complimented on the looks of my car a lot. I got the 2.0T, it has adequate horsepower for running on the highway and passing but gets me great gas mileage on my trips. This is my 2nd Infiniti and I think I will always choose the brand.

Fantastic sports sedan.
The 18 Q50 is the favorite car I've owned. It is top of it's class in performance. All wheel drive system works great in winter. My only complaint about this car is the size of cup holders, which is trivial.
There are 10 matching cars close to your year range.
