Hi Franco!
Yes a T3 is a very exclusive and expensive car in Denmark, especially when it comes to taxes.. ;-)
I dont know of any special offers for T3's here, but you need to get a "no-claim letter" or at least some form of documetation from your italian insurance company stating how many years of claim-free driving you have had.
If you dont have any documentation of your previous insurabce-history you probably start from scratch and that's an expensive solution.
Write a mail with your information and letter from your italian insurance comåany attached and send it to as many companies as you can, there can be very big difference in prices!
If you are still interested in my bikerack for your car, we can work something out, apologies for never getting back to you on your last mail, between relocating from Norway and working and painting my new apartment I have been very busy lately..
