A driving school certificate may help you to reduce insurance. Once you get the certificate, you are equivelent to a 3-year local driver in 3 years. It means you get benefits in 3 years. For a beginer with $2000+ premuin, you may get $100-$200 discount a year.
Insurance is very high for young driver (<25-year old), and even higher for teenage driver. If you bug 2-door race car, you may pay double than usual if you are young driver.
When you bought insuance, declare the car is for "pleasure", around 20000km a year. It would be higher for business or work.
