Once you leave the lot, you are a dirt bad in their eyes.
What exactly did they do to you?
I would have expected to be directed to the parts counter when I returned to the dealership so that I could buy floormats.
None of the many new vehicles we have purchased over nearly 50 years came with floor mats as standard equipment. The brands of those new vehicles include Mercedes, Volvo, Honda, Toyota and Lexus. Floor mats were always optional and at extra cost - same as other options and accessories we wanted. My 2014 Sienna Limited did not come with standard floor mats. I specified them and negotiated their price when I special ordered the vehicle and paid for them and the vehicle when I took delivery.
I should be picking up a new Corvette under the Corvette Museum factory delivery program late this year or early next. Does the Corvette come with floormats? No and I don't want the optional carpet mats. I'll be taking a box of Weathertech floor mats as checked luggage on the flight to Louisville and I will install them before the leisurely multiday drive home.
