expected in a roadster

Comfort isn't usually expected in a roadster, but the Z4 has plenty of it. The 2-seater comes with firm, supportive seats and has a surprising amount of legroom. The available leather is treated with sub-reflective technology that helps keep the interior cool on a hot day. Wind buffeting is reasonable enough at highway speeds to maintain a conversation with the top down, and with the top up it's nearly as quiet inside as a true coupe. The 2-piece top, made of aluminum, opens or closes in just about 20 seconds. Trunk space becomes a bit smaller with the top down, but with it up the trunk has space for two golf bags, according to BMW
