I have apparantly blown my starter motor in my 03 1.8 astra coupe.

Allegedly there is a common-ish fault whereby the ignition key sticks in the third position which in turn stops the starter motor from disengaging leading to burn out.

I was wondering if anyone else has experience this problem, whether anyone can tell me roughly how much it is going to cost me for a replacement part, and maybe even where i could get one?

Would a starter motor from a standard astra fit?

Cheers folks
