I purchased an 09 Accord in July of last year. I was unable to locate the one I wanted with navi at the time. I loved that Accord so much that I upgrade to a 2010 with Navi 8 months after buying my 09! The car is comfortable, handles like a dream, and is worth the money. I've had no problems and have recommended the Accord (both 09 and 10) to many friends.
I love the look with the wing spoiler. Navigation is easy to use. Bluetooth is very clear.
With either my 2009 or 2010 I've have no suggested improvements!
