Why such a huge difference in insurance quotes

[user 8497]

I am in the process of finding my first phev and have been astounded to see the price difference for insurance on the same trim, year and approx milage there is. For example. 2 cars. Both 2019. Both dynamic. Both 2.4 variant. Me an over 60's. But one is quoted at over £470 and the other £260. Same company (1st Central). Can anyone explain????
