Quiet, reliable tank!
By CMMOS on 7/23/2026 12:21:50 AM
Purchased a 2019 Infiniti QX 80 in 2023 with about 40k miles on it. Just passed 100k recently. It’s been a great comfortable SUV. Awesome for winter ski trips to Colorado and summer vacations to Missouri. It has a ton of storage and even a decent size third row. I would highly recommend this vehicle if you’re in the market for a luxury SUV without the costly maintenance of a German brand. - 5.0
Best Luxury SUV owned
By txswinner on 12/29/2025 1:43:18 AM
Been through the gambit and have had no really bad experiences with SUV's owned including Cadillac, Buick, BMW, Dodge and GMC. The Infinity Q80 rates the best so far. I drive about 2,500 mile per month and had the Q80 20 months and have no service issues and the standard maintenance has been super. I recommend the Q80 to anyone who wants a full size SUV with all the bells and whistles. I also recommend the 4 wheel drive option. - 5.0
Outstanding Family Vehicle.
