Any way to offer audition prior to purchase/payment on Audiogon?

I am trying to decide how to offer a complete system, or portions of a system on Audiogon while giving the potential buyer an opportunity to audition prior to purchase.

The sale will be offered as a local pickup only as the equipment is heavy and time consuming to tear down and set up. The buyer will need some time on site to learn.

So, the bottom line is how do I offer a local pickup only sale with audition rights prior to a commitment.

I'm not out to circumvent Audiogon fees, but need to know prior to creating the ad.

I would not be surprised if the answer is NO WAY! If that is the case, how should I proceed with a sale?

Thanks in advance for any input.
