Hiya James!
Don't throw all hope away and convert to manual just yet! Your pictures could have been taken from my car a couple of months ago and I am still a happy owner of a convertible with a FUNCTIONING power hood.
IF the motors are still working, a reasonably priced fix is the following, this is what I did:
From your local dealer, pull rod P/N 54348112787, roughly 30Ԛ£ to replace the bent one. Perhaps also the joint link and inexpensive bolts ans screws needed. Check this link for part numbers if broken:

Then to the main cure! I was lucky to find a fix from the German Ebay. Obviously we are not alone with the mechanics breaking off from the motor, our German friends are offering third-party solutions. This is the exact fix I bought:

It replaces the sore spot with a metal plate, ingenious! A great guy and ships to Europe.
In total, you are looking at very little Ԛ£ and getting a durable solution. If any further questions, I have just done this so ask away!
