When I am spending $40,000 or more on a vehicle I am going to take 10 minutes and do a test drive. I am also going to check the fluid levels as the dealer prep people often make mistakes. I have had low ATF, ungreased control arms, slipping belts, missing tire iron, missing jack, missing spare tire, incorrect side mirrors, and that is with my last 2 vehicle purchases.
In both cases I took the vehicle back to the dealer and refused to take delivery until the problems were corrected. The dealers wanted the vehicles off their lots and off their books and so they made sure the problems were quickly corrected. I had lots of leverage before taking possession of the vehicle and little or no leverage afterwards.
Frankly, you screwed up and now want sympathy. I don't even buy a dozen eggs without checking that none are broken, but maybe that is just me.
