When you have a record year for car sales such as what happened in 2014, you can also expect a record number of auto-loans. Credit reporting bureau Experian says that Americans borrowed a staggering $886 billion dollars last year to finance new and pre-owned vehicles, but they maintain this is no cause for alarm.
 Experian mirrors what Equifax has already said about the possibility of a so-called sub-prime bubble. That is, despite the massive increase in lending, there has been a relatively small growth in sub-prime and deep sup-prime borrowers, which up 3.83 percent and 5.60 percent, respectively. However, the total market share of sub-prime and deep sub-prime loans actually fell by twenty percent.
