I work at Nissan Main office and can tell you they make a fine car. They are pushing right now to increase sales and offering some great buys and financing terms.
My dad works for Visteon and is on Nissan projects right now and he raves about the cars there. They build a quality product, priced competitevly, and they don't look like other cars out there. Go with the Nissan!
I own both Camry and Accord . Accord is definitely superior to Camry in its Mechanics . Smoother transmission and better controls . Newer Camry is better looking but has a bad transmission . If you can wait buy a 2008 honda Accord Hybrid .
