There are several incentives to buy an electric or plug in car, including rebates, perks and tax credits. The type of vehicle you purchase and use determines the tax incentives you get for it and, as the government is keen to promote the purchase of electric vehicles, high tax credits are offered to owners. In addition, depending on your location you can get a specific amount of rebates which come in the form of a check in the mail. Additional perks include access to solo carpool lanes and preferred parking lanes.
