Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
My first car was a gemmini my old man and me were half and half drivers on rego and on insurance. That way you are able to gain a rating.
the only way a young bloke can get full comp insurance under a grand is if they drive a piss weak car, or if they insure the car under a parents name, and list them as the primary driver.
this of course is in fact illegal - insurance fraud. generally insurance companies will overlook it the first time, but if you have 2 accidents in the car where you're not listed as the primary driver (eg if you have it insured under your dad's name, and your a 2nd driver) then the insurance company will do some investigating.
basically they will notice that you've had 2 accidents / claims in a car which you claim not to drive very often. if they notice that your parents have their own cars, and you appear to have this car all to yourself, then they will see it for what it is and reject your claim, and you pay the entire damage yourself, and you get in big trouble with the insurance company, who aren't big fans of fraud.
just remember - insurance companies don't get rich by paying out insurance claims. they get rich by investigating and rejecting claims
