car dealers????

So, I have a growing family and in need of a car... sedan. I finally managed to break it down to a holden or a ford.
We use to own a BMW 3 e46 blah blah blah, but really that meant nothing to me. When I purchased it at the time a was looking for a car that was pleasing to the eye, comfortable to drive and since our young family was usually with me SAFETY. My only suggestion to women thinking the same thought is.... DON'T GO THERE GIRLFRIEND! My husband is usually off to work at 6.15am and home around 4.30, I work full time, it is really hard getting the car serviced and apparently BMW's need it, they sort of insist that you follow it. Well no thanks to the dealership that also sold me a LEMON. On another topic, I even had the BMW checked and like the car buying, lone female I was, the dealer saw me coming. After I paid for the car to be checked(RACV approved) and got the paperwork back, the dealer told me that they had done the identified work to it.... don't believe them. You should always insist that if the car failed the first check then the dealer is to pay to have it rechecked before you sign the documents. THAT IS A MASSIVE LESSON I LEARNT and i hope that women in the same category as myself will learn this lesson cause it is an expensive lesson.
