Dutton Kit Cars and their owners
I found Flux offered better cover than some of the others, not cheaper though.
Leggy, Sierra and Van - all with Flux.
I use Osborne & Sons, not the cheapest (£119) but only by a couple of quid. 13 years with them now. and they insured y daughter while she learned to drive £25 a month
I use Osborne & Sons. My 2 litre Pintos cost me £175 each per year, fully comp. But then (as I recently found out) this is a car theft hot spot.
My only complaint was that when I had the Melos, my insurance needed renewing a week before I put it on ebay, so I cancelled the insurance after just 2 weeks and I got just £72 back from my £175. I had paid for 2 full years before that and only driven it 2 miles. When the girl phoned me to check if I wanted to renew, I had told her that I was going to sell it and she said that it would be no problem as I could just cancel it and get a refund. Yeah, right.
