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.

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.

⭐⭐⭐⭐⭐ Exceptional Service from Joel at The Sharpest
⭐⭐⭐⭐⭐ Exceptional Service from Joel at The Sharpest Rides! I had an outstanding experience working with Joel at The Sharpest Rides in Englewood, CO. From the moment I walked in, Joel was professional, knowledgeable, and genuinely invested in helping me find the right vehicle. He made the entire process smooth, stress-free, and even enjoyable—which is rare when buying a car! Joel answered all my questions with patience and honesty, and there was never any pressure. He went above and beyond to make sure I got a great deal and was happy with my purchase. I truly appreciated his transparency and dedication to customer satisfaction. If you’re in the market for a used car and want top-notch service, ask for Joel—you won’t be disappointed
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.

Great job and fast service.
Great job and fast service. Very friendly. My car looks like new after the clear coating. Thanks
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.

I had a complicated problem with my older vehicle and the team listened to me and took extra time to make sure they fixed it the way I needed it, at a reasonable price.
Best car I have ever owned
Very responsive and utterly reliable. Lots of power. Excellent life saving safety features. Comfortable to drive. The longer I have it the better it works and the better I like it.

Eric was great, as usual.
Eric was great, as usual. This was my 3rd new vehicle through him and I also sent a co-worker in who purchased too. The issue is not with the sales team, it’s with the finance dept. I am still waiting on resolution for an extended warranty I purchased with my new car last month. Shockingly the $$$mistake is in the dealers favor. 2 emails ghosted and no credit back to either my loan principal or my credit card. My suggestion is to just purchase the vehicle there and decline EVERYTHING the finance department offers then run out the door. Sales gets a 5, Finance dept 1 1/2. I will give them the rest of this week to keep up there end of the contract before I envolve corporate.

My husband and I just had one of the best online car buying experiences ever! Liz & Ramy at Joe Rizza Acura are truly amazing! They made the process as simple as could be & went above and beyond to answer all of our questions and help us with whatever was needed, especially considering that they are in IL & we are in NC, and even after delivery of the vehicle, they are still willing to answer questions & help us. They didn't ask for this review but it is so incredibly well-deserved that I had to do it & I highly recommend reaching out to them if you're in the market!

The team at Henry Brown is very exceptional. Purchasing a vehicle from across the country is stressful but my salesman Mike Roberts made the whole process very comfortable. I have spoken to many salespeople throughout my search for a new truck and am very glad i was working with mike throughout the purchasing process. I recommend henry brown for any of your future auto purchases!

great experience!
The guys at Unlimited had just the car I was looking for! As my wife and I approached the car we had our eyes on, we were delighted to see that a dealer had unlocked the car from the remote so we could check it out. Once we were in the car we fell in love with it. As I took it on a test drive I noticed a vibration in the steering and after mentioning it to the team they pulled it into their shop and fixed it on the spot. I am now the happy owner of a Audi A4 Avant Quattro :) Thanks Unlimited for the great experience and a sharp car!
