I was/am in a similar boat, I graduated may.

I was just about to sign the lease for a 13 328xi (these things are a lot closer to the 335 than in the past). Until i shopped around.

Yes I am making good money but it is shocking how fast it goes once you have big boy bills.

Instead I bought my x5 (06 4.8is) put 10k down and it is 200/mo. Much more manageable. You have to factor in insurance as well. Of coarse you will pay this on any vehicle but a lease has to have full coverage and will be more because of its value. You may be able to afford it on paper. But wait until you start seeing how much taxes REALLY take out and how quick it goes every weekend when you want to go do fun things, travel, party, impress girls, build your hobbies, whatever floats your boat.

Saving is a serious discipline and starting off with something like a leased car is a step in the wrong direction.

Just my $.02
