Service manuals

I'd like to buy a service manual for my 2009 Swing. I see some good prices on eBay, but almost all the manuals I saw descibed them as for 2002-2006.

How compatible do you think this age manual would be with the 09 model? If it is just a few difference in fuel injection or wiring I don't think I'd mind. I'm just not sure that spending the whole amount for an 09 manual is worth the extra dollars over the older manuals.

Thanks. On closer cost comparisons it looks like I might only save about $15 for the older manuals, so I will probably just get the new one and save myself the worry.
