PNC Financial Services Group Inc., said Wednesday that its first quarter consumer auto loan portfolio grew to $10.9 billion by the end of March 2014, compared to $8.7 billion the same time last year. The bank also said its 1Q2014 indirect portfolio was $8.9 billion, up from $7.0 billion the same time last year. Auto helped offset a decrease in the bank’s overall consumer lending, which was down by $1 billion due to lower home equity and education loans, as well as seasonal credit card declines
