On opening a door and seeing the Flex interior for the first time, the impression is rich and inviting. Color coordination is carefully managed. Materials, plastics, fabrics, leathers and carpets, are well matched with textures and sheen is nicely controlled. The visual impression is more Lincoln than Ford. No, make that more Audi than Ford. Or, better yet, Audi with a fair amount of good-looking, but clearly faux, woodgrain trim.

The impression of comfort and luxury is reinforced by large door openings and excellent entry-egress to all three seat rows. Seats, particularly the front seats, are chair height, which means you slide across as opposed to jumping up or squatting down to sit. Easy for even the less limber among us.

People-carrying vehicles such as Flex are all about accommodations. Flex accommodations can be ranked in what might be called descending order.

The two front seats, separated by a stylish multi-function console, are more comfortable and accommodating than the second-row seats, which in turn are more comfortable and accommodating than the third-row seats. More luxurious too. Ford speaks of a leather interior. This means perforated leather inserts and smooth leather seatback wrap on the front seats, but only leather inserts in the middle seats (vinyl everywhere else) and all-vinyl seats in back. Leather-accented interior might be a more apt description. (Though, in fairness, other manufacturers do this, also.) That said, all interior materials, including the seat vinyl?s, have a look and feel that communicate quality and durability.

Flex front seats are superb, beautifully shaped and wonderfully supportive over long drives. There is a caveat, though, in the form of fairly aggressive headrests Ford claims are mandated by new federal safety standards. These place your head farther forward than you might be accustomed to, in the interest of reducing whiplash in the event of a rear-end accident. Maybe so, but other 2009-model vehicles we've tried that presumably have to meet the same requirements at least perceptually have less intrusive headrests.

Second-row seats offer generous legroom and basic support good for long trips, and are marginally less supportive and comfortable than those in front. The second-row seats are adjustable fore and aft to create or reduce third-row legroom. They can also be folded through an electric switch to enable third-row access. Push a button in the C-pillar and the seatback folds forward, then the seat cushion folds up. Presto! Full rear seat access at the mere touch of a button! Clever and well done. Another interesting second-row touch is a pair of wedged footrests that Velcro to the carpeted floor and add to overall comfort.

Third-row seating is what might be called occasional for adults, but reasonably comfortable and accommodating for anyone under 5-feet tall. Adults can reasonably hang on for 30 minutes or so. Longer than that, and it becomes confining. This sense of confinement is exacerbated by all rear side glass being fixed, as well as the backlight. Third-row ventilation either has to come from overhead A/C ducts or someone in the second row opening rear-door windows. On sunny days, the third row can quickly become hot and stuffy.

Several Flex interior features are worth mentioning. First is the multi-function screen display in the center stack of the instrument panel. This is in conjunction with Ford's SYNC Hands-Free and Communications System, and offers everything from airwave audio to satellite audio, climate controls, Sirius Travel Link, navigation, hands-free phone and reversing camera. Push-button or touch-sensitive switches are either adjacent to the screen, on the steering wheel, or within the screen itself. Split-screen readouts are available. The reversing camera offers a day-for-night feature, which means that even in the darkest alleys, the rear-view image you see on the screen is as bright and clear as in broad daylight.

Audio quality through the system developed by Sony is excellent.

Taken as a technology exercise, the in-dash screen functions and display are spectacular; the colors, the graphics, the sheer range of capabilities never fail to impress. In practice, there are some limitations. The voice recognition function often takes a couple of tries to get it right. Maybe it's the accent, maybe it's the inflections, maybe it's ambient noise, but regardless you learn to pace yourself giving instructions and have to be prepared to try more than once. Then there are the screen readouts. Some colors (red, for instance) are hard to see in certain lighting conditions. Others are in symbols or fonts too small to distinguish while driving. Still, the system as a whole is a technological tour de force and clearly paves the way for future developments. Our advice: take a passenger along to work all the many functions while you do the driving. It's easy to get distracted when trying to work these systems while driving.

Other interesting features are color-adjustable cabin mood lighting and an optional refrigerator that installs between individual second-row seats on 2-2-2 vehicles. Not just a cooler that keeps cold things cold, but an actual refrigerator that takes warm things and makes them cold.

Another feature worth noting is the optional deep-tint Vista Roof. From the outside, this appears to be a single moonroof over the front-row seats combined with a huge glass panel over the second and third-row seats. From the inside, the front-row pane is a conventional glass moonroof with normal slide and tilt features. In the second row, glass is visible over the right and left sides, with a solid headliner trim panel up the middle. In the third row, a single glass pane extends across the seat from left to right. Second and third-row overhead glass is fixed, with retractable sliding shades to reduce interior heat and glare. Keep in mind the Vista Roof is not available on vehicles equipped with optional roof rack side rails, so anyone buying Flex has to decide between multiple moonroofs or a roof rack.

Behind the third-row seat is a small cargo area about the size and shape of what you might find in a minivan. This is accessed through a swing-up one-piece tailgate. The load floor is carved into a recessed well, which keeps cargo in place and prevents things spilling out but also makes access marginally more difficult than with a flat load floor. Of course, those needing more room or better access can easily fold third-row seats to suit.

Cargo capacity is 15.0 cubic feet with all three rows of seats in place, 43.2 cubic feet with the third-row seat folded down, 83.2 cubic feet with the second- and third-row seats down.
