Jesus, how do some of you afford these cars so young. Take it you live at home still!!!!
Mk5 GTI for myself (oldun) 28 with 5+ years NCB and my fiancee covered as a named driver who is 21, £880 through Brentacre. It was cheaper with Churchill at around £640, but we would have lost more money transferring out of our existing policy, so its as cheap to stick with Brentacre and pay the increase.
Brentacre have unlimited mods policy with no mid term adjustment costs though. So its worth sticking with them for that. Well, unlimited mods for anything that doesnt boost performance.
Worth noting, that on my own policy the cost was around £400.
