Hi, we have a 2010 Mazda CX-7 that has been virtually bullet proof for its life. I am very interested in a Niro EV Premium (2018 leftover) but have some reservations so I am looking for some help. The Niro is considerably smaller then the CX-7 which bothers the wife, I drive a Mini Cooper in the Summer and a Vibe in the Winter so it doesn't bother me. Question 1, how do owners like it on the highway? Is the engine buzzy/noisy at 70-73mph? I really dislike wind noise, the CX-7 windshield was replaced twice and the car was never quiet again, just very annoying so was wondering if that is observed. Question 2, the 16" wheels sound pretty small to me, my daughters Mazda 3 has 18" wheels, I think something like that would have been nice on the Niro. I have found a 2018 leftover about 100 miles away that has been price reduced so we probably don't have a lot of time to decide. Any help would be appreciated, thanks!!
