One way to get much cheaper insurance is to survive to my age!
Adrian Flux quoted me for my proposed 520bhp Elan. No NCB, Full Comp, £25,000 value - £583 - not bad. No one else would touch it. My Range Rover (L reg) costs £150 FC, same as the Robin Hood (both with AF as well). One of the very few advantages of getting older
My kids did the Pass Plus and got one year's NCD straight away. Worth thinking about. Essex County Council will even pay half of the fee!
