General Motors Co.'s (GM) - Get Report warning on 2017 auto sale reverberated through the market on Tuesday as aftermarket and refurbished auto parts makers and retailers rose.

The auto giant's Chief Financial Officer Charles K. Stevens told analysts Monday, June 26, that it expects industrywide light-vehicle sales to be several hundred thousand units under previous estimates, noting a 7% decline in year-over-year used vehicle prices. "The market is definitely slowing," he said.

A slowing auto market may be bad news for new vehicle manufacturers such as GM, but as drivers keep their cars on the road, auto parts sellers could profit off the rising number of clunkers in need of repair.

More used car sales could lead to a greater demand for car parts, and many top sellers saw their share prices make gains on the day's news.
