On the flip side, how many people are ever happy paying list price for a car? We hear it plenty, that a dealer should knock at least 5% off a new Nismo, or that a Zed up for £6k should sell for £5.5k. In general, no-one expects to pay list for cars anymore, so you can't really blame them for the cheeky offer approach.
But yes, taking the p*ss haggling on cars that cheap.
