the body shop just sent my car to the mecanics and they said that the speedo could of broke by topping out the car or from the accident so my warrenty doesn't cove it, but it also could of been from the 50mph hit in the rear end i just recieved......it this something that i could fix, in my garage? Or is it best to have them do it? How much could something like that be? And is that a gear driven cable or electronic? Any help would be appriciated.
