Go to two Hyundai Dealerships that are owned by competitors > get the 'best' deals you can at each place > say you'll think about it > go back to each place on Thursday 31/1/13 and see if they'll drop their prices to boost monthly figures (from remaining stock) > create a reverse auction if you have to, saying, "Well such-n-such dealership is willing to let us have this for $*****. What can you do"?
You may then hear the response, "If we can match that and supply extra optional extras, will you be willing to do business now"?
