Recommendation for car comprehensive insurance?

Hi! On 30.04.2010 I can pick up my new Audi A3 Sportback. Currently I am looking for a good insurance. That means “good” with regard to performance and price. The ratio has to be right. At first I thought I would be quite sure with the HDI insurance. But then the new value compensation of 12 months somewhat bothered me. I would like to have 18 months. So I came across the Huk or Huk24. Price was also interesting and the services seem 18 months of revalued damage is there (at an additional cost even 24 months). I am disturbed by something that I have already heard from some that Huk is a bit problematic in the event of damage. Do you have any further suggestions? What would be with the WGV for example? Are compared with the Huk with regard to P/L, but a little unknown… Greeting & many thanks! A3sebb
