I think you've gotten a lot of great advice so far, just want to make sure you don't get your hopes up based on your statement of a August arrival, and you have to make a decision soon. Are you basing plans off an agreement with a dealer and not just what you're seeing on their website? It would be unusual for one to be arriving in August that isn't spoken for, it's also unusual that you have time to make a decision. These cars are largely spoken for many, many, months ago, they only come up on the lot when someone backs out of a reservation, when that occurs they are usually sold quickly, like the first person to answer the phone gets it.
