Other than the initial issue(s) I had with both my 2020 Explorer ST and our 2023 Aviator, We have been very happy with both vehicles. That's why I traded the Explorer for the Aviator. The long term mileage has been great (20.9 mpg over 6K miles) and 23.4 on our trip back to FL. The ride is much smoother than the Explorer, and overall, it's much quieter, even though I have installed a Borla exhaust, because it was too quiet when starting up!!
Only complaint I have had is with the 22" Goodyear tires. We solved that with Michelin Pilot 4 SUV Summer tires. Now the steering is responsive and more wandering or training when the road is old and worn.
Best of all, being Black with the Jet package, it's gorgeous and we get lots of compliments. Highly recommend.
What has surprised me some, is that at our Clear Lake Iowa summer home, we see many more Aviators and Navigators than we do here in Naples. Several neighbors have one or the other.-+++
