General Motors to offer car sharing via mobile app and OnStar

General Motors has partnered with a San Francisco-based start-up company named RelayRides to enter the car-sharing business.

There's a 2015 Ford Mustang convertible on the way, too

Almost immediately after the Ford Mustang debuted, buyers could choose from three body styles -- a hardtop, a rag-top convertible and a fastback (which actually came out a few months later than the hardtop and convertible). We already knew that the 2015 Mustang will arrive as a fastback (sorry, notchback partisans), but Ford has just announced that a drop-top version is also in the works. Pictures of the convertible sport a shiny "5.0" badge on the side and and chrome "GT" badge on the back, but we assume all the standard engines -- the 5.0-liter V8, 3.7-liter V6 and that new 2.3-liter EcoBoost turbo-four -- will be offered.
