Approximately three months since its world premiere, the new 4 Series Coupe has been incorporated into BMW USA’s online configurator. Math starts at $45,600 for the base 430i in rear-wheel-drive form, but today we’re talking about the (temporary) range-topping version with all the bells and whistles. The M440i xDrive Coupe begins at $58,500, and as you’re about to see, you can add nearly $15,000 worth of options with just a few mouse clicks.
