"Car dealers have joined other retailers to embrace Black Friday as a big sales driver," said Jessica Caldwell, Edmunds.com director of industry analysis.
Black Friday is expected to set the pace for potentially record-breaking car sales in November.
The projected November sales will be an 8.3 percent decrease from October 2015, but a 2.5 percent increase from November 2014.
Car shoppers will find Black Friday specials in many showrooms and they don't have to wait for the busiest shopping day of the year. Most of the sales have already started.
The Dodge Black Friday Blockbuster Sales Event dangles various combinations of zero-percent financing and cash-back deals in front of shoppers. The promotion includes the 2015 Charger sedan and 2015 Grand Caravan minivan.
Chevrolet dealers are touting the Chevrolet Black Friday All Month Long promotion, with 20 percent cash-back deals on such model-year vehicles as the Cruze, Impala and Malibu sedans, as well as the Camaro SS sport coupe.
Not every automaker will benefit from the Black Friday sales frenzy, however.
Edmunds forecasts that Volkswagen and Audi sales in November will be down 14.4 percent year over year, with VW brand sales alone falling 26.9 percent over the same period.
Edmunds says: Car shoppers should be prepared to take advantage of an abundance of Black Friday deals.
