come on Jasmine - you are meant to be doing this yourself and it will be based on your lectures - this is pretty obviously Contract ( and not state trial or Treason)
so you need to review the steps leading up to a contract
invitation to treat and so on .... you will have been lectured on this or at your level you wouldnt have a question on this
you will also need to go over Sale of Goods and whether a top speed makes it unfit - new one - the one I did was 1893 and the answer would be no unless it were specified
and
the rarely used misrepresentation act 1971 ( or whenever ) allows you to unwind a contract if misrepresentations have been made leading up to it. - which seem pretty clear here
so the short answer is - contract, yes
but this is an essay q
and is meant to test your ability to quote cases and construct a logical argument....
by the way did you buy the book on ELS for 66p ?
I bet the answer is no
