From nearly 10 years in the car business,
mainly as a Manager...
UPSIDE:
You get exactly the options / colors you want.
Nobody will have a chance to "test-drive" or abuse it.
It will be as close to perfect as possible (no tiny scratches, etc...)
Very low miles upon delivery.
You MIGHT get to take advantage of better rates / rebates - you get what is available when it comes in, not current offers.

If you are in a state that charges property tax on vehicles, you will not have any on your new AV for 2002!
DOWNSIDE:
You will not like the wait.

You MIGHT have to settle for higher rate / less or no rebate - again, you get what is available when it comes in, not current offers.

You will HATE the wait.

Waiting really sux...
YES, you definitely WILL have to agree on a price when you order, and you will have to make a small deposit, and either fill out an application, or otherwise show them that you are able to complete the transaction when the AV comes in.
ROY - Sorry for the difficulties you have had at times with dealers! They can be a real pain.
However, there is no reason whatsoever that a buyer cannot get the BEST price on an order! Assuming same vehicle, same price, the dealer will actually make more profit (net) on the sale if you order than if they have had it on their lot for over 30 days, and will make much more than if they have to get it from another dealer for you. There are other benefits to the dealer as well, but they do not merit further discussion in this topic.
OH, rest assured - they WILL try to convince you to take one from their inventory, or will offer to locate one for you (or both) but that has to do mainly with the fact that if you order, they (Dealer, Managers and Salesperson) will not get credit for the sale, OR get paid until you actually take delivery! PLUS, once you take delivery with "your" temp tag or plate on the vehicle, for all practical purposes, the deal is done. When you order, there is still the chance that the deal will not fly.
For info on getting a great price on your new AV
the EASY way, see
How did you get the best price?
For a realistic idea of what you might expect on a trade-in, see
Trade-in Values
That is geared toward trading a 2002 AV for a 2003,
but there is good info there for any trade-in situation.
WHATEVER YOU DO...
make sure that you do get an AV!
