I know this topic has probably been done to death by now, but im gonna ask anyway

Having just changed jobs i lost the use of company van. And after the canning the cossie took on the way to TOTB, i no longer have any Brakes I have therefore bought myself a lovely new Vauxhall Ashtray 1.4 to use for work. My question is, how do i insure it cheaply? My current insurers, Adrian Flux, will only start a new policy and not stick it on top of the Cossie. They want over £400 for a 1.4 astra tpft. How do you lot insure second cars? Can anyone recommend a company that will do a good deal on 2nd cars? Thanks for any help
