Congrats on completing college. When I was out of college, I bought a used 335i. However, up in Canada they are much more expensive. If you can afford a new 2012, I would do that. Otherwise, keep in mind housing. I also went with a used one so that I could still qualify for a mortgage and I bought a condo. My condo is much more of an investment than a car!
