Now insured for around £200 after a bit of to and fro and I wouldn't recommend ever bothering with Performance Direct for insurance, even if they do come out cheapest - guess what - can't complete the payment for the policy online, so go to phone and up jumps the policy.
Went with Be Wiser for insurance. All good.
Have now spent some time at the helm of this thing, starting to learn RWD, which is great fun. Definitely needs some limitation in the slip of the diff. Can't do donuts without it.
