P.O. Box 2000
Bloomfield Hills, MI  48303-2000

Ladies and Gentlemen:

         We have  represented  Core  Industries Inc, a Nevada  corporation  (the
"Company"),  in connection  with the  preparation and filing with the Securities
and Exchange Commission (the "Commission") of the Registration Statement on Form
S-3 (the "Registration Statement"), for registration under the Securities Act of
1933,  as amended  (the  "Securities  Act"),  of a maximum of 857,283  shares of
Common Stock, $1.00 par value per share (the "Common Stock").

         Based upon our  examination  of such  documents and other matters as we
deem relevant,  it is our opinion that the shares of Common Stock covered by the
Registration Statement,  previously issued and outstanding and to be sold by the
Selling  Shareholders  listed  in the  Registration  Statement,  have  been duly
authorized and legally issued, and are fully paid and non-assessable.

         We hereby  consent to the  filing of this  opinion as an exhibit to the
Registration  Statement.  In giving such consent, we do not admit hereby that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act or the Rules and Regulations of the Commission thereunder.

                                      Very truly yours,

                                      D R A F T

                                      Honigman Miller Schwartz and Cohn
