2015 EXl V6 coupe automatic w/navi opportunity

Hello. I'm new here and would appreciate your feedback about this. There is a 2015 V6 coupe at a dealer here. It has 4600 miles on it and their asking price is $25,000, not including doc fees and tax. We asked and dealership says it is a dealer demo. That seems like a good price. We have an appointment to drive it for "a few hours" this weekend. It is a CPO as well. Not sure if it's considered new or used at this time but it would be warrantied with what is left of the manufacture's warranty as well as the Honda certified. Dealer will not let us have it overnight.
Does this sound like a reasonable deal? Are buying demos a bad idea?
Thanks in advance for your ideas.
