I got some more information on this and its good news.
I spoke to a gentleman named Brain who is the spokesperson for this program. Accordingly the program details will be finalized on April 9th, and he expects that individuals can take advantage of upto $2500 per vehicle, and the details such as the list of cars, rebate amount for buying, leasing, lease duration etc.. will be posted on the same website sometime later in April, and the program is mostly likely to take effect for purchases from May and beyond. There is an application form - that will be made available in the website - that individuals have to apply and get approved - and the grant is limited and so it will be on a first come, first served basis.
