Avis Budget says smoking in its rental cars will set you back a whopping $250

Nonsmokers who travel often find themselves frustrated once they unlock the car they've just rented at the airport. After a few hours of lounges, gates, and airborne cabins mercifully free of secondhand smoke, travelers slide behind the wheel and wonder how nobody at the rental agency has noticed that the interior smells like a Las Vegas casino.

Fans of fresh-smelling car interiors, rejoice: Two of the biggest players in the rental-car business are banning smoking in their fleets, starting next month, and will impose a $250 cleaning fee for anyone who chooses to light up in that freshly scrubbed Ford Fusion or Dodge Caravan.
