This shouldn't be a diesel debate. I rather not go that way, it's a simple as that.

Now back to the topic, I think I'm really leaning towards the 50i and have just about 2 weeks to make up my mind. Some things I also like on the 50i is the 20" wheels on the sport package, the exhaust pipe tip design looks a lot cleaner, the functional lower grills opposed to the black plastic fillers (this looks really cheap), and on the Sapphire Black I like the look of the full aluminum grill. Plus performance wise is no contest.
