Vroom Vroom Vroom, an eco-conscious car rental site, announces its official U.S. launch, bringing stateside consumers fast, hassle-free and environmentally friendly car rental booking service.

The new site enables customers to make reservations with all major rental car companies in more than 2,000 U.S. locations, including major airports, city centers and smaller regional towns.

Vroom Vroom Vroom also provides carbon offset credits with each rental, at no cost to the customer. Renters get the benefit of no cancellation restrictions and a lowest price guarantee that offers $10 if a lower rate is found elsewhere.

One lucky renter each month will get their entire booking free, with no extra fees.

www.VroomVroomVroom.com offers price comparisons and vehicle selections like luxury cars, SUVs and convertibles.

The site has a “Geek Travel Guide”—a list of 25 Web apps for road-trip planning including maps, travel search engines, resources for business travel and tools for finding parking lots, radio stations and the best gas prices.
