Bad after Sales Attitude

My wife and I bought a VW EOS at this branch. <br> At this stage the only thing that we complained about was the front passenger mirror which was cracked.<br> I complained to the sales guy and he said he will fix it.<br> <br> We drove the car for a month then we noticed things about this car did not add up.<br> - The panels in the car were loose<br> -The wiring underneath the seats were loose<br> -The carpets were loose<br> -The roof is leaking <br> -The airbag light is on. <br> <br> I complained about this issues but i was told by the General Manager that it was wear and tear. How can panels get loose within a month ? This does not add up. My guy tells me that this car was probably involved in a major accident..
