The new options arrive a year on from the offer of an expanded M Sport Plus package, keeping the two-door models ahead of the pack until all-new replacements arrive.
Depending on the model, enhancements include styling and comfort upgrades, along with mechanical and safety tweaks. BMW promises as much as $15,000 in extra value for the 3 models, and up to $4000 on the 1 models.
