Better-than-normal sales conversions are continuing into early March, according to Ricky Beggs, vice president and managing editor of Black Book.

According to Beggs, entry mid-size cars and upper mid-size cars were the best trending segments at +$30 and +23 respectively. "[They] are following the trend for these two segments for this time of the year in 2012 and also 2011," according to Beggs, who added that near luxury cars have also seen a modest increase of +$2.

However, overall the average car  segment change was at -$23 and for the previous four weeks the average change has been -$25, representing a pretty stable market for the cars, according to Beggs.

"The truck segments are performing even better as seven of the 14 truck segments increased for the week with an overall average segment change of only -$3," Beggs said. "This is the best retention level since the +$5 change level from the week ending December 21, 2012. For the past four weeks the average segment change for the trucks has been at -$17."
