not bad at all, flux were the cheapest by a mile for me in the ep3, but for the dc5 they were not competitive.
i ended up going with A Plan in the end which was cheaper than sainsburys, greenlight, flux etc etc.... i got £575, 25, 5 years no claims protected, 10k a year, like for like mod replacement too.
but for the s2k, no one could match SKY insurance:

they mirrored my 5 years no claims which no one else apart from Chris Knott insurance would do, A Plan refused to insure me on the s2k even though i have the teg with them too....
so it worked out at £450 for 5k miles with my uncle as a named driver... not bad
i will deffo be trying SKY next year (i hope its not affiliated with the murdoch cronies but it most probably is haha)
edit: sky also give 20% discount to car club members, so i assume that helped
