RelayRides, the peer-to-peer car sharing company, announced a new ‘carcierge’ feature available in select areas as of March 14 to improve convenience in booking a rental vehicle for customers.

After entering the location and times for the rental, customers will be able to choose from vehicles automatically suggested from RelayRides as owners respond to the rental request. The company also added the ability to filter car search results by make and price range, as well as for owners to respond to potential renters with alternative times.

RelayRides said the features, usable on desktops and smartphones, will help customers who are flexible with the type of car they need.
