Call me old fashioned here, but a mildew smell and a "Lawnmower in the shed" smell...good golly, what is THAT?!....and "Pretty nice" shoulnd't be used in the same sentence. What exactly are your criteria for that particular compliment?
Anyways, beware the stuff you can readily see (or smell), b/c it portends what cannot be seen...typically folks take care of the obvious if they don't, they cannot be trusted to do the more important, invisible maintenance issues...like proper oil and filter changes, etc. Even a Honda needs good maintenance, otherwise, what's the point in owning one, surely not the style, or the ride.
Take a closer look at this fine automobile in daylight and see if it's really such a deal. Personally, any sign of chronic wetness is enough of a reason to run the other way.
