Timing is everything. Do your homework and collect all your facts during the first part of the month. Start some negotiations through the middle of the month. Negotiate all the way until the end of the month with multiple car dealers. Then only visit the car dealerships at the end of the month. If they are on the edge of making their factory quotas, you might be surprised what kind of deal you get. It's been know to even get a vehicle below the dealers cost when they are desperate to make their numbers. Timing is key. You must find the right dealership at the right time.
Start the process with a new car price quote.
