Legally, I've got to give them a chance to put it right. I'm regretting the purchase now, though I do love the cars in general.
With the immense drama leading up to the purchase of your Mog I cannot state that I am surprised to see this comment.
You will have read time and time again that new Mogs require fettling. I am aware that this was covered by many in your introduction topic. By mentioning your legal rights I would question whether you are prepared to go through the bedding in process that these vehicles require.
Good luck.
