There is only one sure way to get a delivery date firm enough to plan on.
Call Peter and ask him. Wait 3 days. Call Peter and ask him again (voice slightly disguised). Wait 3 days. Get a friend to call Peter a third time and ask him. (he'll know your voice by the third time).
Take an average of the three delivery times (I guarantee they'll be different). This will be your "ERA moving delivery average" and I it
will be moving.
Divide your moving average by 365 and multiply by the current price of a "Grinder" in New Britain.
Send $5,000 and start the whole process over again. The one thing you can say for certain using this method is that at the six month mark, you will be six months closer to getting a truly amazing car. Its worth the wait.
