In all my years of owning these things, I've never once regretted a purchase. Most people drive BMW's for the drive. They are an amazing driving experience. People that whine and complain about problems and expense of repairs need to get out of the BMW and get into a Honda.

Yes we all have our moments when we complain about problems and having a 2013 anything with lots of problems is absurd but expected for a totally newly redesigned vehicle. You bought a first year production of a vehicle....NEVER EVER EVER EVER EVER do that. It's unfortunate that you are having so many issues but I'm guessing you are going to have many more recurring issues throughout your ownership experience.

With my first BMW, I learned how to turn a wrench really quickly and have for the most part and now for sure with these forums been able to do a lot of work on my own or end up shelling out a bunch of money for repairs. It's the way these cars are. They're fickle and needy.
