McLaren MP4-12C Spider

The glass window behind the passenger compartment acts as a wind deflector when the top is down. But it’s a power retractable unit, and can be lowered at any time, even when the top is up, to allow more air (and sound) into the cabin.  (David Undercoffler / Los Angeles Times)

If all this sounds like a nice way to introduce a sunburn to your bald spot, be prepared to pay about a $30,000 premium over the 12C coupe’s $231,000 base price. Dealers are taking orders now and deliveries will start in late December or early January, with some priority given to current McLaren owners.  (David Undercoffler / Los Angeles Times)
