Standard equipment is decent, including wireless Apple CarPlay and Android Auto, synthetic leather upholstery, power-adjustable front seats, and parking sensors.

All-wheel drive costs $2,000 more, coupes run about $1,500 extra, and convertibles kick off at about $60,000. 

Which BMW 4-Series should I buy?

That depends on what you’re after. If you’re looking for style and aren’t concerned with power, the 430i models are just fine. To them, we might add real leather seats, metallic paint, and adaptive cruise control, which can nudge the price upward by around $5,000.

If you’re looking for performance, a $65,500-or-so M440i coupe offers acceleration on par with with full-on M versions from a generation or two ago. Again, you’ll likely want to budget $5,000 or more for optional features. 

How much is a fully loaded BMW 4-Series?

M4s start at $80,500, give or take, while the Competition trim with its 50-hp bump and fairly harsh suspension is another $4,000. An all-wheel-drive M4 Competition convertible runs at least $96,000, and adding features such as full leather upholstery, carbon-fiber trim, matte paint, a surround-view camera, a head-up display, and a heated steering wheel can push the price to well over $100,000. Less appealing—at least to us—is the $13,900 Carbon Package with its extensive carbon-fiber trim and ceramic brakes. Oof. 

BMW is also offering a limited run of M4 CS models with 543 hp for about $125,000. The CS cuts weight with carbon-fiber-reinforced-plastic body panels, exterior trim, and bucket seats, as well as a titanium muffler. It’s stiffer thanks to a front strut brace, and it gets uprated brakes beneath 19-inch front and 20-inch rear forged wheels.
