Following news of a strong Black Friday and better-than-expected November sales, a new report on the auto industry is showing signs of a strengthening consumer. According to findings on auto financing from Experian, Americans took out a record number of auto loans in the third quarter, and interest rates slid to their lowest level in at least six years.

The report, released Wednesday, showed the average amount borrowed for new vehicle loans in the third quarter was $26,719—an increase of $756 compared to the same period in 2012. It's also the highest average amount financed that Experian has recorded since it started tracking auto loans in 2008. (Read more: Auto deals pull in Black Friday shoppers)

The average monthly payment for new car buyers climbed $6 to $458 in the third quarter.
