I purchased the V6 Coupe b/c I needed a car that was comfortable, fast, and reliable. It also has Nav which I love (I drive a lot b/c of job). The Nav is very easy to use and I like the touch screen for all other controls e.g. AC, Audio, Nav, Trip computer etc. The car drives well, corners ok, but it has a lot of pep in it. 0-60 just under 7sec, stock. Leather could be better, drivers side bolster is showing wear, but its covered under extended warranty so I will be getting it replaced. Service not expensive, tires not bad, less than $100 each. Console does not click closed properly, started after 16 months.
Nav, Acceleration, Rear spoiler, XM, Audio is impressive, comfort. I am 6'6" I have to lean back to fit b/c of headroom, but plenty of leg room.
More reliable console. Audio jack input for mp3. Better leather for front seats.
