Finally designers built a two-seater with a trunk large enough to be practical. We aren't saying you'll be sneaking any friends into the drive-in theater in the back of the M Roadster, but you could get a couple of soft bags and maybe a set of golf clubs into it for a weekend getaway. Designers allowed for an additional cubic foot of space that can be had by raising a panel in the trunk if the top is in the raised position. Had BMW not taken up a large amount of trunk space with a can of sealant, a compressor and a hose, you could likely get two bags of clubs in the trunk. The M's exhaust routing and size precludes a spare tire, necessitating the compressor and sealant. The trunk opening is large and liftover is no issue as the lid rises to a vertical position well out of the way.
