Price depends on risk - that is what insurance is about.
When I lived in Belgium (2005-2008) Audi A4 2.0T Quattro cost me 1600€/year. I had more than 10 year non collision history, had alarm and garage. I was over 35. Same time my wife's coworker 25 year old guy who just got license and bought first car (2500€ POS, no garage, etc.) paid 3000€/ year.
Now in Finland insurance with same coverage costs a bit less than 1000€/year. If I lived outside Helsinki region price would drop about 100€/year.
Our system allows 60% bonus for mandatory basic insurance (covers innocent parts damage, it takes 12 years to gain max bonus - complex system) and 70% for voluntary that covers your own stupidity etc. (insurance companies give maximum bonus immediately to get customers.)
Out of curiosity I checked what new MY 2012 A4 would cost me: Mandatory insurance 811€/year (no bonus) and with best voluntary insurance (includes 70% bonus) 1905€/year. I would get several discounts: my other insurances are in the same company 230€, I have other cars (clean history) in this company 80€/year, I was making order via Internet - campaign -20% 299€/year. Total for me (41 year old man) would have been a bit under 1300€ /year.
This insurance would have been valid in whole Europe expect voluntary part (car theft, vandalism, own stupidity) wouldn't have been valid in certain parts of eastern Europe.
