DARCARS Volvo Cars

My girlfriend and I were looking to buy an additional car, one better on gas mileage and still safe and comfortable, so we decided to narrow it down to Mercedes, BMW, Volvo and Audi. After spending some time looking at used cars, we found a nice 2005 BMW 530i with under 29k miles for a reasonable price at Darcars Volvo. Since she refuses to drive an automatic, this was truly one of the few cars we found that fit our criteria (it is a 6-speed). Initially, the staff was very friendly and although not knowledgeable about BMW, at least they seemed to be willing to help. The Sales Associate (Sam Amin) even gave us his cell phone number to call him if we decided to buy it and he would come in on his day off (he used the line that someone else was coming in to buy it tomorrow from out of town so we had to act quick). When we took it for a test drive, I noticed several marks (some of which are to be expected with a used car) and the fact there was no owners manual in the glovebox. The reason I looked was because he didn't bother to go over the car with us at all and I wanted to look up how something worked. He assured me that day that the marks would be taken care of and that he would get the owners manual for us if we decided to get it. The car itself was wonderful outside of these facts, so talking about it that night, we decided to get it. The next day we went in to pick the car up and this is when the web of lies and talking in circles was exposed. The interest rate for financing wasn't what the Sales Associate told us, so we decided to look past that and just put more cash down on it than initially agreed on doing. When I inspeted the car, I found it was washed, but had not been cleaned (ie. the marks I pointed out to him were still there) so his response was to bring it back at a later date and they would take care of it - again not a deal breaker but definitely arousing my suspicion about him and the dealership. As we are signing the paperwork, the Sales Associate brings his used car manager over and informs us they don't have the owners manual but will promptly order us one and have it shipped to us AND that they only have one key for the car, but that they only cost $90 at a BMW dealership, so he'll knock another $200 off the price for us. I now look at my girlfriend and she says that since this was the best car we had found, just to continue with it. We get in the car (which we absolutely love) and drive it home. Two weeks later and still no manual or phone call, so I call the Sales Associate to check on the status. He says he doesn't remember who I or my girlfriend are, doesn't remember having a used BMW that he sold, but he'll look into the records and talk to the parts department and call me right back. Another 2 days and no call so I called the dealership asking for the GM but get put on with the used car manager - I didn't even ask for the USED or NEW manager so now I am really wondering what is going on at this dealership. Anyway, I tell him about the issues and his response was "when you buy a used car, you get it as is, nothing else. As far as Sam (the Sales Associate), he has had 6 heart attacks and by-pass surgeries so his memory isn't too good anymore." He then said he would look into this, and if indeed we were told about the owners manual beforehand, he would order it for us. This absolutely blew me away, to the point my anger turned to disbelief at what I was just told and became speechless. He just gave me some absurd reason for the lack of memory on his Sales Associate's part, but then said he would find out whether he promised us the manual before signing - but he couldn't even remember the car??? Well, it has now been another 1 1/2 weeks and yup, you guessed it, no phone call or owner's manual.
