if you buy the car now you do not have to tax it, "but" you cannot park it on the road, it must be in a garage or on private land. now at this point you do not have to insure it "but" if any thing happens to it ie vandalism/theft you are not covered. if you do insure it "before" you pass your intensive course it will cost a fortune. you sound like a young person? the best and only advice i can give is don't be hasty, pass all your tests then get the car.
