This all-to-often occurrence is bad news for the general car-buying consumer. This unfortunate incident reiterates the need to include additional terms in the car purchasing contract about what is and is not expected of the dealer, including removing protective film/plastic and washing/detailing upon delivery as well as consequences (IE monetary amounts) for not adhering to these agreed additional terms. (How many of you (me included) have read ALL the fine print terms and conditions on ANY purchasing contract!).
Unfortunately, most, if not all dealers will not agree to them and will consider you a pain-in-the-butt for including them OR refuse to do business with you. You as a consumer need to decide if it's worth the risk of not getting the vehicle you want or finding a "more accommodating" dealer/seller. If the dealer refuses to accept or even consider such terms, which, I assume, are legal additions to car purchasing contracts in most states, it would raise a red-flag about their customer service and service-after-the-sale.
Many states have a "cooling-off" or "grace" period where a vehicle purchase contract from a dealer/seller can be voided; usually it's three-business days, which will allow the buyer to collect their full down-payment or deposit.(Done to prevent divorces and killings by spouses of their significant other who has purchased a vehicle out of want or inpulse without consulting the other party of the debt/expense being incurred by the buyer). A lawyer and subsequence law suite should be a last resort (and expense!). Chances are you may loose some of your incurred cost in front of a judge. Most courts justices side with tax-paying/people-employing businesses. Not saying it is fair or blind justice; just a "fact" of business law in many counties and states.
