I once had an employee that walked into a Ford dealership, saw a new F150 he liked and when it came time to talk price and money, opened with, "How much are the payments?".
Another, went to the dealer and bought a new fully loaded diesel powered F250. The tax alone was about $10,000. He was 25, single, no toys, living in an apartment in town. In other words, no practical reason to be buying that much truck. 
It's not some sort of drug that the dealers put into that new car smell; I have similar stories from employees and used cars. 
Only common denominator: they were all guys. 
Leads me to wonder, who do car lots make the most margin from: men or women?
