insurance training requirement

I'm selling as soon as I get it back from the annual.  Mine has metal wings so the empty weight is about 940.  I have the STD for 1320 giving me around 380 pounds useful load.  I weigh 220 and 10 gallons of gas is 60 so unless my buyer is really skinny, we can't go together.  How do potential buyers do test flights if they need 5 hours of training before going up?

 

I get my insurance through AOPA's broker, Assured, who shops it around to various insurers.  This year's cheapest quote ($1,350) requires me to get 1 hour of flight training from a CFI in my make/model of airplane (415-C).  The next cheapest ($1,450) has no flight  training requirement for me but a 5-hour requirement for any other pilot I allow to fly it under the Open Pilot clause.

Is this common?  Any way to get around it?
