Over the years there have been guitars made by fender and others to celebrate a different american iconic brand like for example a Ford Mustang. But today I found this tasteful guitar that BMW Australia had made to celebrate an anniversary of their M series cars.

Made me wonder if Alembic has ever been comissioned by a company to make a guitar or bass, or any other stringed intrument for them to commemorate an anniversary of theirs. Excluding this one we know of from a few years back.
