provide support
         within the prospectus for the statement that you will enter the
commercial market "with
         the world's first long-range electric step-in van developed for mass
production." If the
         statement depends on the term "mass production," please add disclosure
to explain its
         meaning. If an evaluation of third-party manufacturing capacity is
relevant (e.g., high-
         versus low-volume production, single- versus multi-party assembly),
please add support
         or characterize this as management's belief.

share program will be
         subject to a lock-up agreement.

which each class is
         entitled.

us as to why you
         no longer believe it is required.
        We remind you that the company and its management are responsible for
the accuracy
