I must have rented the same one from DCA as you. It's now got 5K miles.

Absolutely love the parking sensors. This big a car still isn't great for parallel parking but those beeps from the curb sensor that get more rapid as you get closer to another car or the curb are perfect. Not sure if it had auto parking.

Also didn't know how to turn on the blind-spot warning so couldn't test it's accuracy. Only other car I've driven with this was the Volvo S80 (Hertz) and it's BLIS left something to be desired.

The small extra sunroof for the rear seat seemed not very big or useful.

In the console there's not only a usb but also red white and yellow RCA plugs for video- so I guess you can play video on the touchscreen dashboard. A video screen for the rear seat would have been safer and the rear has less functions than one would expect in a car many would have a driver for.

The not only heated but air-conditioned (!) seats were novel.

The car was fairly tight handling- for a really big car- and the power steering was exceptional.

The keyless operation was very nice. I expect it to be standard very soon on most cars.

The glitter in the black paint shows really nice in bright sunlight.
