Love this Car
by Tim D on 9/14/2026 5:14:10 PM
First off....Infiniti Metallic Blue is a beautiful color! I bought the car really based on the color! However, I had already owned a 2014 Q50 and loved that car as well and my son is still driving it with no issues!! A great car mechanically and a very good car overall...sporty lines, plenty of power with a twin turbo V6 with 300 hp.....fuel economy is right at 25 mph consistently. AWD system handles Chicago snow and ice very well! And it handles extremely well. I owned two BMWs in the past and they are fantastic handling cars....I love them! However, they are much more expensive to maintain compared to Infiniti. Other than normal maintenance, I have had zero problems! I would recommend the car to anyone and the value overall is outstanding!! - 5.0
