My BMW 330xi is, to say the least, a fantastic car. Because it has the largest engine available in 2006 (3.0L straight-6), it sounds great and goes like hell. I've put 90,000 miles on it on all different kinds of roads and it runs like day 1. The sound system is the upgraded version that BMW offers and sounds great, even 10 years later. The transmission is /pretty/ good, I'm a manual transmission kind of guy so the automatic isn't my ideal transmission but it has sport and semi-automatic modes which is nice when getting onto a highway because in second/third/fourth gear this car flies.

There is not much that I can say about the car that is bad. I couldn't be happier with my purchase and for my first 'grown-up' car, I definitely don't regret anything about the purchase.
