Welcome along! In regards in insurance, just go onto gocompare and check. They have altezza rs200 in their drop down box and i found the cheapest are Adrain Flux for me. I am from NI myself and when i was 20 with 3 yrs NCB they were looking £2500, then as soon as i turned 21 it dropped to nearly £1000! But all depends exactly where you live to be honest.
I would assume at 19 you would be looking £2000 plus but you never know until you shop about. Good luck
