We were looking for a larger alternative to my wife's Lexus RX330. Wife wanted more upscale vehicle, but no SUV. Flex is technically not a "luxury" vehicle, it gets very close in terms of leather, materials and technology (I am referring to the "Limited" model). Interior was in quality to her Lexus RX. The use of space inside the vehicle is superb, with many functions and useful touches. The seats are extremely easy to fold down for storage. The ride is very nice (better than the Lexus RX). Suspension is soft, but firm enough for good handling. Takes corners better than any SUV, little body roll. A solid vehicle - highly recommend.
Comfortable seats, lots of storage. Also, this vehicle handles very well. You do not feel like you are driving such a large vehicle. In terms of handling, it is close to a Lexus SUV, and far superior to a Escalade, Mazda, or other SUV.
This vehicle needs a telescoping steering wheel. While it has adjustable foot pedals, the steering wheel is too far away for any driver with long arms or over 6' tall. Ford doesn't put these in any of their cars for some reason -- must be a safety issue.
