When I start the car theres a thud. This does not happen each time. on 2004 Cadillac DeVille

This occurs after aproximately 10 starts. It makes the thud/metallic sound then its fine. I dont know if its the starter but someone suggested it may be that. Is that an expensive repair and can i avoid the dealership service costs.

Thanks Greg. Does driving it with this problem do any further damage? Either repair is a huge cost and I would not want to add to the problem. I suppose as it worsens the thud will be more frequent.
