The resurgence of the coronavirus and an economic crisis led to the Spanish new-car market plunging 21 percent in October.
Registrations for the month fell to 74,228 from 93,954 in October 2019, according to industry association ANFAC.
October had one less selling day than the same month of 2019.
All sales channels suffered declines, with sales to rental companies down the most at 46 percent as the tourism industry continued to suffer because of travel restrictions. Registrations by private customers were down 23 percent and sales to companies fell 16 percent.
Total sales in the first 10 months are down 37 percent to 669,662.
ANFAC hopes a government scrapping package called Plan Renove that became fully effective on Oct. 20 will prevent the market from plunging even further for the rest of the year.
The 250 million euro ($291,000) program encourages consumers to replace cars older than 10 years with newer, more energy-efficient vehicles.
Incentives range from 800 euros for gasoline and diesel vehicles to 4,000 euros for zero-emissions vehicles such as full-electric cars. The program will run until Dec. 31.
