Remember all that money you were going to save on taxes thanks to that LS 600h L you bought last week? You don't? Good, because it doesn't exist. The federal tax credit for new hybrids is limited to a certain number of vehicles and Toyota has hit that mark. If you're the owner of a Toyota or Lexus purchased before October 1st you're still eligible (after that you're SOL). Of course, you still qualify for up to $3,000 in credits if you buy a hybrid from Ford, GM, Honda or Nissan. [Houston Chronicle via HybridCars]
