I also know nothing when I made my first BMW purchase. I started lurking on forums months after the pruchase and tried to learn about it as much as I could. I don't regret owning a 2010 328i E90. In fact, happy I owned one
The same reckless buying experienced happened again to me last month. I purchased a 2013 Merc C250W before doing homework. Oh well, I am learning the hard way
