They're trying to rip you off!!!
I say that because they know darn well what company it's from. They "think" it's from National Warranty? They think it is well accepted by Acura? Hogwash. If you really want an extended warranty, then I highly, HIGHLY recommend you demand the one from American Honda. The price is fixed for all dealers, it is guaranteed to be accepted at any Acura or Honda dealer, and it is what they should have offered you in the first place. The only reason they could be screwing with you like that is because they're making more money on the fly-by-night warranty they're trying to stick you with.
Don't let them do it!
