Ridiculous insurance renewal costs

[embee]

There will always be a variety of experiences with insurance companies. Personally I have been pleased with how both Aviva and LV have answered the phone promptly (UK call centres), been very competent in dealing with questions regarding the various cover aspects, and have been reasonably priced. They are by no means the cheapest, but I'm happy to pay a bit more if I'm fairly confident they will be decent to deal with. I currently have policies with both.
 There are some horror stories of dealing with some reasonably well known companies.

(50, Cornwall, switching from 61 Hyundai i20 to new Jazz SR)
Having gone online and did a "Moneysupermarket" type quote, I was expecting my insurance to go up quite a bit on switching to my new Jazz - most quotes were over £400.
However when I went to switch the insurance over with Admiral (did it online), was very surprised to only be charged £40 something more (of which I think £10 or £15 was the admin), so still well under £300.
