>>  Try an auto specialty magazine, some people * need * a car,
and can't wait,  other people would wait until the deal works for you,
particularly if the price drops.  There is a stigma about cars that are
" sold "  but delivery is deferred, the rationale is that some motor head
moron will beat the s**t out of the car prior to delivery.
Unfortunately this does happen, I've seen both sides of that coin.

    A local car dealer would give wholesale price whenever you want
 Smaller dealers would be a good bet, if it's an attractive car.

    Local gas stations might consider a deal where they get a commission
after the sale, this way they can make money, without investing any.
 I know of a [ former ] local repair garage that did so many of those
deals, they later became a used car lot, and sent the repair work out.
