General Motors' U.S. sales increased for a fourth consecutive quarter, and Toyota's sales increased for a third consecutive month in June, a feat attributed to recovering auto inventories, reported Automotive News Research & Data Center.

For the second quarter, the Detroit-based brand reported:

• A 17% rise in Chevrolet sales

• An 18% increase in sales at GMC

• A 48% spike in sales for Buick

Overall, GM reported retail sales advanced 15% and fleet shipments rose 34% during the second quarter.

It ended June with 427,000 vehicles in U.S. dealer stock or in transit, up slightly from 412,000 at the end of the first quarter.
