Ahhh car salesmen, I worked for a North East car supermarket for 3 years (not in a sales role). It was a real eye opener, as kwerk said there are tactics that can help you, the place I worked for example ran on a standard calendar month for meeting sales targets. Approach them a week before their sales targets and play hardball and you'll get a deal. Also if it's a car supermarket you're visiting, the cars in stock are usually financed on a 90 day rotation (money is given to the dealer to buy the car, the repayment to the finance company needs to occur within 90 days). So if you are patient and notice a car coming in to stock that doesn't shift after 2 months, then you're also going to be in massively stronger position. However never let the salesman know that you're aware of the time in stock etc as they will just cut you off to spite their face. Also as a rough guide, at the place I worked their was generally a 1k - 1.5k profit margin on each car. When a salesman sold a car they would get 250quid on top of their low wage, sell with finance add another 50 quid, sell paint protection another 50 quid - do all three (sell, finance & paint) another 50 quid. So with that in mind play the game, the salesman is more likely to give you a decent sale price if you agree to paint protection etc that may mean he get's more money in his pocket.
