what irratates me about car dealers is all the fee's they try to get you on when they sell a car to you.
I'm not talking about tax and title fees, but optional add-on's that the dealer does that are not needed and other fees added at the time of sale.
For example, dealers will often do an undercoat sealer on a car which adds to the cost. This might be great in Michigan where is snows all the time a cars rust out, but in the south where we live, it never snows! It's just not needed.
all kinds of other stuff like that they put on the car as "dealer installed options".
Another example. sales guy and I agree on a price of X amount plus tax and title. When I go in to sign all the paperwork, they've added a $250 "business transaction fee" that they say is required for them to fill out all the paperwork to complete the sale. I tell them that's not my problem and I didn't agree to the fee and refuse to pay it. Only when I get up to leave do they finally waive the fee as they were about to loose their sale also.
Makes you wonder how many people they screw this way.
Leaves you with little respect for the car sales industry.
Your 3 to 8 percent is skewed by the fact of these add on fees and dealer kickbacks from the manufacturers.
