When I was 20 it cost me 3500k to insure a Suzuki swift gti,i think at under 25 you will pay premium prices no matter where or who u use and then they wanted an approved alarm put on.

Im with shannons have been great so far

Ask your parents to put it under their name and write you into the drivers list? If that's an option...

That Doesnt work anymore ed. Not for years. Having had worked in insurance before a lot of claims were denied over this or they were made to pay the propper premium based on the youngest driver.
If you cant afford the insurance you csnt afford the car.

Get third party fire and theft for a couple years to build up your rating if you stay claim free when you swap to full comp.
