The following video is part of our "Motley Fool Conversations" series, in which industrials editor/analyst, Isaac Pino and industrials editor/analyst Brendan Byrnes discuss topics across the investing world.

In today’s edition, Isaac and Brendan shed light on the sudden emergence of a potential threat to Zipcar in the car-sharing business. Recently, Car2Go, a subsidiary of Daimler, has gained traction in multiple cities and plans to go nationwide in the very near future. The business model differs from Zipcar since Car2Go offers one type of vehicle and is built for point-to-point transportation in short increments. Is it a threat to the leader in car-sharing? Maybe, but Zipcar's leadership will need to continue to turn on a dime and find new revenue streams. Perhaps the more intimidating aspect of Car2Go is the deep backing of Daimler and the presence on what is likely the most attractive continent in the world for this industry -- Europe.

Isaac believes that Zipcar, as a growth play in the transportation industry, has to penetrate international markets to succeed. This might be a ways off for Zipcar, but there's another American company that has already cornered perhaps the hottest international market with a proven business model and an incredible management team.
