Auto sales still riding uphill- pushing the industry towards their strongest monthly pace since before the recent recession. Both General Motors and Ford posted stronger-than-expected June sales. GM's were at their highest level for June since 2008. Ford had its best June since 2006. Chrysler's were in line with forecasts- but were its best June total since 2007. It's all about pent up demand -says Edmunds.com's Senior Analyst Jessica Caldwell.
