You can't use "self" in the "def" line. Here is how I usually accomplish 
what you are trying to do:

class Car(Basicsprite): #car class
    def __init__(self, speedarg=(0,0)):
        self.speed = speedarg
        Basicsprite.__init__(self)
    def move(self, speedv=None):
        if speedv==None: speedv = self.speedv
        self.rect = self.rect.move(speedv)


But maybe somebody else can suggest a nicer way to do that.
