FREDERICK, Md. -

November data compiled by the National Auto Auction Association showed average prices dipped both year-over-year and year-to-date for 2012.

NAAA economist Ira Silver determined that November prices softened by 3.0 percent compared to the same month a year earlier. Through the first 11 months of 2012, prices ticked 1.8 percent lower.

Moving to a look a volume data, Silver found mixed directions when reviewing the November information.

The association determined volume climbed 3.4 percent year-over-year in November. However, the volume rate was off by just 0.1 percent through that span of 2012.

A macroeconomic reading Silver also mentioned in his latest update pointed out real consumer spending, which rose 2.1 percent year-over-year in November. The year-to-date analysis showed a 1.8-percent increase.
