Surley that really depends on the car. If a car is advertised for 10,000 then the price is 10,000. His best price will depend issues you can point out for the car, eg higher than average milage, scratches to paint work, obvious smoke odour, not a full service history etc etc etc. Of course there is nothing to say the dealer will not claim that these are already factored into the 10,000 price and any further reductions that 'his boss' could make would be coming straight out of the business margin and would therefore be from the goodness of their hearts.
But now, to contradict myself, I would say you should hope for a 8 - 10% reduction towards the end of the month, after thrashing the cars reputation and condition and showing him the other cars you can get for 8 - 10% less and flashing him a quick view at the check book as you transfer it from one pocket to the other following a 80 second silent staring match with the spouse and as many ragged kids as you can gather in the background causing mayhem in his new car showroom. Then walk out if you dont get it.
Repeat untill you do not need to walk out.
You need to be sure of your ground, that what is on offer is not in fact good value without holding out for more that the 8%. The only people who know what the car is worth are a salesman willing to sell at a given price and a buyer willing to buy at that same price. Without this situation pertaining there is no way of saying what the car is worth. You can only get the best deal you can negotiate. same with the salesman. Any help???
