What's the "protection package"? Price the same thing on Honda's website and you end up with roughly the same price ($292 including tax without the protection package). I'm guessing that package is 5 or 6 hundred bucks? So essentially he offered you MSRP. You can probably still do better.
From Honda.ca:
DX-G, manual, no options:
4.9%, 48 months, 2K down (3100 due on delivery), $9132 residual = 292/month including tax.
Again, adding $13/month to get to $305 probably works out to that protection package being about $700.
