I don't think the answers are going to be much help to you.
Due to the arrival of a dog, I'm about to change my car from my beloved 500S TA 105, probably to a Panda 4x4 or Trekking. Fiat aren't taking orders for Trekkings atm pending the arrival of the revised model, so I'm waiting.
I checked out what it would cost me to insure a panda, and a few other models I'd considered. I used a comparison website, put my details in, then changed the cars to compare, it's really easy to do. I'm 50 with a full NCB. However, I always pay the added premium for NCB protection. I do not go for the lowest quote, rather the lowest quote from a company I'd trust - AutoExpress do an annual survey.
My quote for the Panda TA 4x4 was £250. I got quotes for other models I'd considered included the Mini Clubman Cooper, Suzuki Swift Sport, Fabia Estate 1.2 TSi 110 ranging from insurance group 6 to 19. Everyone single one of them came back in the £250 to £260 range!
Your age, driving history, location, job, whether it's garaged etc have much more influence than the car (within reason).
