I have never heard of a cartridge being lent out. If it is new, then near half it's value is gone, just mounting it and playing a few sides. A demo model risks damage.
The only way it would seem possible is to lend out the dealers demo model and take a credit card payment for it's value, against safe, undamaged return. That risks the dealers relationship with a customer, if the charge is enforced.
