I had a great experience with RAC car insurance. I didn't expect them to be that cheap, but I realised from some of the online stuff I've read, that because I don't use my car much and drive off peak, then I saved much more with them. I bought breakdown cover from them last year, and I ended up with a further £25 off my price, which was a nice touch!
I had to add a quick review as I was so impressed with the quote I just got from them. I received my renewal last week from Norwich Union. They wanted £399. I used Confused.com to hunt for a better quote, and I was happy to find the AA offering the same thing for £349. I actually bought that insurance. However, just on the off chance this morning I checked the RAC (which Confused.com had not checked) and I was gob smacked. The RAC offered me the same insurance for £249. That is a saving of £150 on Norwich Union and £100 on the AA. This was for Comprehensive car insurance cover with an additional driver who has a speeding conviction. It also includes a courtesy car. I have cancelled my AA and gone with RAC. I haven't made a claim yet, but given the reviews on the Review Centre site, they are very similar for AA and RAC (and awful for Norwich Union). I'm made up!
RAC car insurance came back as the cheapest quote for me on a search engine (less that £180), and I have always paid £300 - £400 before.
I called them to check that this was correct, to which they confirmed. The customer service agent went through all the details with me, added a couple of extras on, and it was still less that £200. That was the deal for me, and I am very happy with the service they gave, and the price I'm paying.
