Test drive the 328i, it might be a deal breaker.
You will be getting less power with no real weight savings (428@3470lbs vs 335@3545lbs vs 435@3610). The coupes are notoriously heavier across the board, unusual as that may seem. But your power to weight ratio goes down.

If I had to have a 4, I'd get the 435. There was no comparison on the 328 and 335 power wise and the 335. Both are nice, but unless you looking for higher gas mileage, I think you will regret loosing that much power.

To me it wasn't about 1 sec quicker in 0-60. It was about the way it delivers power. Effortlessly in comparison.
