We didnt get a chance to drive one yest like i wanted, we went bed shopping and that took most of our time.
Im sure the aviator competes with luxury 3 row crossovers such as xc90, q7, mdx, xt6, rx350l, qx70 and if you push it, the x5/x7(its closer to size and mission to x7, but i think bmw wants x7 to compete with nav) and gle450/gls450(same as bmw). Also, to get those nice interiors, new tech and great engines on those vehicles(mainly europeans), you have to include their lux pkgs which balloon the price, otherwise their base interiors and features are pretty comparable in feel and content.
Though id like to druve one, for the miney, i think id still prefer a nav. The front seats are the same, but your sacrificing room in the second and esp third row. Your sacrificing cargo room as well. The only three things id want in the nav are the window shades, ventilated sec row seats, and air suspension(the air glide suspension is being dinged by critics, the ones able to compare say the air suspension is best) which im sure it will get next year in 2021my or during its mid cycle. Optioning up the aviator reserve 2 to what i want, im paying 75k+, but a nav reserve with everything i want is 86k and i think the nav has a better front end(ave has a better rear end though).
