Chapman BMW on Camelback

I was skeptical about this used car dealership and my skepticism turned out to be true. Before, I elaborate on my experience, let me provide a summary: Try to avoid this dealership as much as possible. For some reason their new car department has good reviews so, I am not sure how good they are, but their used car depart is filled with [non-permissible content removed] or very ignorant people who are unfit to be a salesman. Here is my detailed experience: I browsed online and chose a BLUE bmw X1 2017 that was quoted for $33,725 in truecar.com. After expressing interest in this listing, truecar sent me an email with the breakdown of price, which included the usual crap like Document Fee, Dealer prep, and Vehicle Theft Recovery Etching. The final quote (excluding tax) was $34,804. So, I entered the dealership around 6:50pm to test drive this vehicle. Unfortunately, I found that this vehicle did not have the safety features that I wanted. So, they showed me another vehicle; a BLACK bmw X1, which was about $36,700. After taking the test drive, they quoted a final price of $38,800. Subsequently, after long conversations and the usual negotiation process, they agreed to a final price of $36,500 (including taxes and fees). So, we entered the usual phase of credit history checking, deciding loan rates/banks, pulling out my insurance policy, etc. I signed a bunch of documents saying “I accept the price”, car fax etc. The entire process took about 2 and half hours. Now, here comes the fun part, around 9:30pm the sales person (let me not name him) comes and tells me that they made a mistake, and the quote of $38,800 was on the BLUE car (i.e., the first car) that I initially came to see and not the BLACK one that I test drove and actually intended to buy!. He goes like “I am sorry for taking your time”. Wow! Now, I don’t know whether to laugh or to get irritated. I understand mistakes do happen, but this! There can be only two explanations to this: (a) they are heavy [non-permissible content removed] or (b) they are extremely ignorant, in which case they are not fit to be a sales person. I will leave the judgement to the people who are reading my review. Additionally, I am not sure how the BLUE car, which has a quote of $33,725 in truecar.com get ma final dealer quote of $38,800! Now, I don’t care if the dealer does not accept my negation, that is totally fine, but you cannot scam people with such dirty tricks. Alternatively, if this was a genuine mistake, how can a price of $33,725 in truecar.com turn out to have a final quote of $38,800?
