S: Looking for suggestions: need time for pre-buy

Well, I lost out on a chance to purchase a nice plane because I wanted
a pre-buy and someone else just wrote out a check unseen.

What do you think of this approach: Offer the seller a reasonable
amount to hold the aircraft until a pre-buy can be arranged. If the
results of the pre-buy indicate major problems, money is refunded.
Unfortunately, this approach does not take into account any price
negotiation.

Anyone have a preferred approach they could share? - Mike
