I just bought a Trek FX 7.3 yesterday from a local bike shop here in Maine. I was told it was a 2010 model, I even had the sales rep check to make sure it was. She flipped the bike over wrote down the serial number and went to verify it, she returned and said it was a 2010 bike?
After getting the bike home I emailed Trek the serial number. Today I check my email and Trek states that it is a 2009 model, built on the 099 day of 2009? I called Trek and talked to the rep who emailed me to make sure, and he said its a2009?

The list price for the 2009 and 2010 is 639.00, they sold me the bike for 579.00. This is why I was concerned in the first place.
What should I do?
