Get input via Input.GetMouseButtonDown to continuesly update

Unity Engine

Im trying to make a car move when you press a box. At the moment im using

function Update ()
{
if(Input.GetMouseButtonDown(0))
{
ray = Camera.main.ScreenPointToRay (Input.mousePosition);

if (Physics.Raycast (ray, rayCastHit))
{

if(rayCastHit.transform.name == “Throttle”)
{
new MessageCarThrottle();
}
}
}
}

to move the car but it will only do it once per click. Is there a way to check if if(rayCastHit.transform.name == “Throttle”) is being held down?

Use GetMouseButton instead of GetMouseButtonDown.
