Car dealers are flush with SUVs just as the economy is slowing.

Auto makers are rolling out new models of crossovers and sport-utility vehicles but SUVs are Bumper-to-Bumper on Dealer Lots.

Sales of crossovers and SUVs are slowing, while models are sitting longer on dealership lots before being sold and companies are resorting to more sales promotions to keep inventory from piling up, analysts say.

And yet, auto makers are getting ready to roll out even more sport-utility offerings in the next few years, further packing U.S. showrooms.

Industry executives don't anticipate buyers will swing back to sedans en masse. But analysts say demand for crossovers and SUVs is topping out amid a broader slowdown in U.S. auto industry sales, and the market share for these models isn't likely to grow too much beyond its current size.
