P.S.
The way to solve the "cashiers check" being for the incorrect amount is to have several of them in denominations such as 10K, 2K, 1K, $500, etc. up to the max you will go, you mix and match to make the amount. Allows you to negotiate and prevents spending more than you intend. Helped buy a 289 Cobra this way some years back.
