Chrysler Corp. says an unspecified number of its dealers will have Peugeot and Citroen cars in their showrooms, but stops short of saying whether a merger with the French automaker is in the works.

Chrysler owns about 14 percent of the French company, which loaned the No. 3 U.S. carmaker, $100 millon in March as part of Chrysler's overall $3.5 billion and package.

The agreement was among the Chrysler Loan Guarantee Board's list of requirements for Chrysler to meet in order to qualify for $1.5 billion in federal aid.

In a statement confirming the agreement, Chrysler said Monday that negotiations with Peugeot-Citroen continue on several other industrial agreements contemplated by the two carmakers as outlined in a February 1980 memorandum.

Included in those possible joint ventures is an agreement by the two to produce a Peugot-designed passenger car at Chrysler plants. The car would be sold under the Chrsyler and Peugeot-Citroen names through their respective distribution markets.

Chrysler also confirmed that an initial set of agreements to purchase mechanical and automotive parts from Peugeot-Citroen could be reached "in the near future" Chrysler also is interested in purchasing Peugeot's four-cylinder diesel engines.
