From any dealership really, the last week of the month. You see, the dealerships have quotas they need to reach for each month - if they're seriously behind in sales for the month, they're going to be more willing to work with you for your business. Also, do your homework. If you're shopping around, get quotes in writing. This makes the best offer at another dealership a solid starting block for the next dealership. Often, if you can't negoitate price, negotiate your financing rate, add-ons (6-disc CD changer, navigation, rims etc.) MAKE SURE TO BRING YOUR WRITTEN QUOTES WITH YOU!! Have a blast buying your new car!
