Neimans Marcus has released a limited run of fifty customised BMW M6 convertibles, and provides a comprehensive package for buyers that includes trips to the German factory plus meetings with some of the designers. Delivery of the car is taken directly from its Bavarian factory where buyers will be flown business class in Spring of next year.

All the M coupe goodies are there, including the 500hp 5.0L V10 and M Variable Differential Lock combined with an electronic damping control system. The seven-speed sequential shifter with BMW’s Drivelogic shift-mode provides an acceleration figure of 0 to 60mph in just 4.5 seconds. The NM version will have an exclusive ruby black paint-scheme with a matching black piano gloss trim inside, and the 16-way adjustable seats also receive unique golden brown merino leather upholstery.

Considering all the unique appointments that the NM car has, its $139,000 price tag is not that unreasonable especially since there are only fifty of them. Interested buyers will need to contact the authorized BMW dealers because this is one product you won’t be able to buy through the catalogue.
