It is not uncommon for Tesla to put more cars on sale when it wants to meet its delivery figures, especially towards the end of the year. However, this could be more important than usual. This is the latest and best chance for Tesla to make the most of the total tax credit. Sales will not necessarily fall when credit declines, but the company will probably not want to lose potential buyers who may run away with less.
In other words, you may be able to get a Tesla before the $ 7500 tax credit falls within 2 weeks, even if you have not placed an order yet.
