It's okay to cheat on your car... if only for a weekend. So says the new ad campaign from Avis Rent a Car. And we agree - especially if you're taking the wheel with Avis Where2, where customers can take advantage of enhanced traveling features with a Garmin nüvi 780. Available to rent with any Avis vehicle, this handy traveling assistant with MSN Direct puts traffic conditions, fuel prices, weather reports, movie listings, local events, news and stocks at your fingertips. According to Avis, renting a car should be an exciting adventure ... but don't let your everyday car know that. Watch the clip below that depicts an old, dirty (and, dare we say, jealous) Saab wondering what type of fancy traveling tools Avis will provide its owner while he's away.
