The M4 Convertible is offered in a single trim, only. There are two optional packages. The competition package offers beautiful-looking 20-inch wheels. The Executive package offers LED headlights and a heads-up display, which can be skipped unless you need the extra luxury. The major decision would be to chose between the 6-speed manual which makes the M4 fun to drive or the 7-speed dual clutch automatic which is much easier to live with.
