next year ý will come to england to study....
and of course ý will buy a car but someone told me that the insurance for the sport cars are too high?is it real? if ý will buy porsche or m3 how much will the insurance cost approximately?????(model 2000-2003 boxster)

If you are a young guy it will cost you a lot. But it varies many times depending where you will be in UK. Cities=big bucks. If you are going for a Porsche or the like joining the club (Porsche Club GB) will save you plenty. For my classic 911, quotes ranged from 550 (via club) to 1600 sterling (general company).

Best way to get a good idea is to fill in the online forms for some brokers here.

what club?
how could ý join them?

try:

There are plenty of online brokers - just search. You will need to give them a uk postcode (zip code) so they can quote you.
