Hello I'm hoping you could advise me which car insurance company to choose from

I have used money supermarket to get the cheapest car insurance quote and it has come up with 6 insurance companies that are the cheapest

Autotrader

Yes insurance

Hsbc

Swinton

Budget

Post office

I would like to know from fellow members which insurance company to go with that offers the best overall service

Is it also best to take legal cover?
