2009 Nissan Altima 3.5 SE 4dr Sedan (3.5L 6cyl CVT)
Got it loaded minus nav. Only owned the car for a week with almost 200 on the clock. The ride is wonderful and the power is exceptional. It feels very athletic yet has the capabilities for a family car that I was looking for. I rated it slightly lower on build and reliability because I already have a squeak by the back seat and a strange clank in the engine compartment by the driver's side firewall. Almost sounds like some spring mechanism resetting. It only does it after each start up after cooling down when you are just starting to drive off. Very strange.
3.5 power. Silky smooth tranny. Was skeptical of CVT, but test drive won me over. Love the gadgets I got for the price. Athletic handling on highway.
As of right now, not much other than the two noisemakers noted above. Maybe a tad more back seat room to compete with the likes of the camry and a blue tooth system that automatically recognizes your phonebook.
