2005 Porsche Cayenne Tiptronic AWD 4dr SUV (3.2L 6cyl 6A)
The only car on the road that can clearly please the owner, the passengers and the ones lucky enough to see it drive by.
I think the most impressive feature would have to be the exterior. It is in fact the most expressive car on the road. And now with it's four wheel drive, the Porsche will be on the road in all kinds of conditions, stealing the attention from all.
I cannot think of any way this car could be improved. Porsche has mastered the perfect automobile with style and safty.
