Fun fact: you no longer see former hearses being driven around as somebody's daily driver. Why? For the past 20 - 30 years hearses are mostly ordinary minivans, with the characteristic "curlicue" design on an insert that covers the rear-most side windows.

When the funeral home is done with the hearse, the insert is removed and the minivan is sold as an ordinary used vehicle. Since it appears to be a normal car there is no deep discount on its price, and sellers aren't required to disclose that it used to be used for hauling dead bodies around.
