Can some one elaborate if there is Nummi discount? and how much?

Secondaly How much is Tax Credit and for how long?

Can't help you with the first question.

Currently the tax credit is $2600. You have to purchase it by Sept. 30 to get the full credit. For six months after that (through March 31, 2007) you get $1300 and for six months after that $650. It disappears on Oct. 1 2007. Of course that assumes that Congress doesn't make any changes to the law.

Many thanks!! How abt Prius?

The tax credit is the same for Prius.

IRS tax credit for Prius is a bit more. See this link
