I´m not sure I should go for a brand new 2008 Honda Civic EX sedan (not the hybrid, the regular gas) or a used 2006 or 2007. If anyone out there knows what improvements Honda made to this car over this years, I´d love to know! thank you!!

I have an '06, and the only difference is different interior color options depending on your exterior color (ex. '06 and '07 black could only be had with and ivory/tan interior), now you can have a grey or black interior with black exterior.

Also, with '08 models there is the option to get leather interior, which was not available on the '06/'07 models.

Great car either way!
