I pay £361.00 FC, (3YRS NCB), on the 94' SuperS with everything declared, (and that's a lot these days). 2010 policy Sky threw in my last upgrades of Omex, Jenvey ITB's and a Gripper LSD for no additional charge.
My standard 96' 1.3GX with LPG conversion costs £353 this year with 4YRS NCB with Admiral, everyone else wanted around £420 on renewal, (up from £287 last year).
Except for exotics, it seems that most cars when you pass 30years of age seem to cost around £400 per year FC regardless of insurance group. As Balloo2u sais, I can get insurance on a Pulsar, Evo, Subi etc for near enough the same price as a K11 which, considering a K11 1.3 has a base group of 5, is quite odd on a group 20 motor.
