Welcome to UKSO mate. For some strange reason GTs are about half the price to insure than a Glanza (for me anyway), even though its basically the same car Try a few quotes on gocompare, usually admiral & elephant are the cheapest. If you put in the reg and it comes up as a Corolla then change it to a GT My insurance was 1100 - 1200 (cant remember exactly) 19 years old, 0ncb, low risk postcode, with mods on, i was main driver & parents as named. Just a few months ago by the way.
