What nuance does the -han suffix add to Pyyntihintahan?

The -han suffix indicates that a piece of information is already known to both the speaker and the listener, or is an obvious fact. By attaching it to the subject, the speaker is acknowledging, "The asking price is too low, as we can both plainly see," before explaining the reason (the rust).

Why is the price described as matala (shallow/low) rather than halpa (cheap)?

In Finnish, just like in English, a price (hinta) itself cannot be "cheap" or "expensive"; it is described as "low" (matala or alhainen) or "high" (korkea). You use halpa (cheap) and kallis (expensive) to describe the actual item being sold. Therefore, you say hinta on matala, but polkupyörä on halpa.
