Pleasantly surprised after my first refuel for new (to me) RR.

I purchased a pre-owned 2024 RR a week ago and am pleasantly surprised with the fuel consumption after the first fuel stop. I think Ford reports EPA mileage as 14 City/18 Hwy. So I got 18.5 mpg in 90% in-town driving. Now I'm eager for a road trip to see how it does. I didn't buy the RR for its efficiency, but happy with it so far!
