You need to very carefully audit the deal sheet. I had two instances of "mistakes", on the financial line items, always in the dealers favor. As a third problem, when I bought the car out from under the lease, Lexus of Glendale used the Lexus Financial Services buyout quote from the previous month, likely resulting in my paying one month too much. But I discovered this after the deal closed and Lexus of Glendale won't even respond. Additionally, it took six months and several complaints to Lexus USA to get my registration which should have been done immediately. I was actually driving illegally with expired tags! At the time of purchasing the car, I asked for the paperwork to be provided for home study since I didn't want to sit in the dealership during the Covid period trying to get through the paperwork. They would not provide me with the documentation until I came in to close the deal. These people shouldn't be allowed to run a Dairy Queen much less a Lexus dealership. I recommend you bring your CPA with you, if not your lawyer, as well.
