No worries mate i wouldnt try and help if i didn't want to.
Really sorry to hear how its gone, but to be honest the way it went round in circles i did have a feeling it was going to be something fairly big wrong with it, that list is exhaustive to say the least, and just goes to show you yourself would of really struggled to git it all right, and clearly the garage that worked on the car were a bunch of fuckin clowns!
You're doing the right thing by breaking it though, hopefully you won't be too much out of pocket if any, and next time you can spend a bit more and buy a really nice one and hopefully you will enjoy owning one
