70k miles over 4 years is not bad. Had to be driven regularly to get there. Pull the equivalent of Carfax, see what repairs have been done, recalls taken care of, etc.
As far as price, is that in US or Canadian dollars? If in Canadian, it is about the right range in US $. Still, might be worth less in Miss, cant speak to local conditions. You can bargain based on maintenance that would be needed soon, lack of warranty, etc.
