Domestic passenger car sales dipped slightly for the first 10 days of June, largely because of the cancellation of a buyer incentive plan by General Motors Corp.
However, Ford Motor Co. and Chrysler Corp. registered gains. Ford sold 47,881 cars, posting an 18.6 percent increase over the 40,383 cars it sold during the same period last year.
Chrysler said it sold 20,622 cars, a 4.7 percent increase over the 19,684 units sold during the same period in June 1981. Analysts attributed the sales increases at Ford and Chrysler to the continuation of their discount and extended-warranty programs.
Meanwhile, American Motors Corp. said it has extended price cuts on Jeep and passenger car models ranging from $750 to $1,000 through the end of the model year and has extended its five-year or 50,000-mile Buyer Protection Plan 5 and a $500 base price reduction on Spirit, Concord and Eagle models until July 12.
GM has about 60 percent of the domestic auto market. And its decision May 31 to scrap its 12.8 percent financing program for new car buyers affected the latest overall sales rates of the domestic industry.
GM reported sales of 100,967 cars for the first 10 days of the month, a 6.6 percent decrease from the same period last year, when the company sold 108,082 cars. GM sales for the year are down 8.6 percent from the same period of 1981 compared with year-to-date declines of 6.6 percent for Ford and 13 percent for Chrysler.
GM's drop in 10-day sales marked the first time since last April 20 that its 10-day sales haven't risen from a year ago.
Altogether, the five companies building cars domestically--including AMC and Volkswagen of America--sold 173,748 cars in the June 1-10 period, down from 173,936 a year ago. According to auto analysts at New York-based Paine Webber Inc., domestic car sales were moving at a seasonally adjusted annual rate of 6.4 million units in the June 1-10 period compared with 6.6 million during the first 10 days of May.
Ford analyst L.R. Windecker said the seasonally adjusted annual rate of domestic car sales fell to 6.2 million for June 1-10 from 6.5 million units for May 1-10.
Chrysler continues offering an auto warranty covering its products for five years or 50,000 miles of service. The sales incentive program is a remake of a similar lure Chrysler dangled before its customers in 1962.
Ford had offered a 5 percent discount and two-year warranty on 10 lines of its economy and mid-priced cars sold between April 4 and June 6.
