Transferring your old license plates to your new vehicle is usually much cheaper than purchasing new license plates for your new vehicle.
If you already have your old license plates and the old license plate is in good condition then there's really no need to get an entire new license plate.
I always just transfer my old license plates from my old vehicles if I get a new or almost new vehicle and it's always been cheaper for me to transfer my old license plates to the new vehicle.
I usually have to pay a $20.00 to $30.00 fee to transfer the old license plate to the new vehicle and it can vary depending on vehicle and the state you're in as to how much the license plate transfer fee is.
