A reasonable alternative for BOTH buyer and seller. Make the test drive one of the LAST step in the process.
So, agree on price, buyer finance etc lined up with sale "subject to"....
Typical "subject to" are: Inspection satisfactory to buyer (performed by buyer or inspector chosen by and paid by the buyer) and test drive satisfactory to the buyer.
Done this as seller, buyer and many many times as mechanical inspector for the buyer.
Sure, if major issues are found during inspection or on test drive, the price is renegotiable.
