@vamsi_vk - ask the sales reprentative to document that via an IRS website. There is nothing on the IRS website that states that. If he can't provide proof from the IRS, it is hearsay.
On new EVs there is no limit to how many you can purchase in a given year and maintain eligibility for the tax credits. You still have to have tax liability (look at Line 22 of your form 1040) to get the credit.
On used EV's, there is a limit of one every three years to get the tax credit.
