A set of spanners you're having a laugh !!
What are you expecting out of a reply like this? You've bought a Mini, they require significant effort to keep running. That effort can either be your own for which you require some basic tools or someone else's for which you need money (and quite a lot of it).
This very thread is proof that even if you only want to do very simple jobs you still require some basic tools (and there's nothing wrong with that, not everyone likes tinkering with cars many just like driving them). Posting that there's no point in buying any because you don't know how to use them seems like a contradiction - you're already trying to do some work and finding that you need tools.
What I expected was information a possible spanner sizes that's all
