I've gone with the Toyota Insurance for mine at £594 with 8 years no claims. I had other quotes from Direct Line £1200 with multi car who insure my Type-R, then was quoted £1500 by Adrian flux who insure my Impreza. I was told it being the A90 bumps up the premium quite a bit. As for the number plate, I asked the dealer where they would mount it and they didn't know. There is no holes or other obvious mounting on the front as it is. I'll be looking to get my detailing, ceramic coating and PPF done prior to delivery date as the place I looked at can collect the car on a trailer from the dealer and take it back.
