FGS. Why do you want 'high performance'? Basically every car built in the last 20 years is high performance - as in light, fast and fuel-efficient too - compared to the sorts of cars many of us learnt on in the '70s and '80s. The only place for 'high performance' is on the racetrack, not on our suburban streets and motorways thankyou very much.
The P-plate rules aren't made just to inconvenience people. They are there to provide some control over new drivers to hopefully lessen the likelihood of them maiming or killing themselves and/or other people, while they build up driving experience and road sense which takes many years to accumulate. Being issued a driving licence is a privilege not a right.
trust me mate i am on green p plates down in Victoria stay away from any thing that's a sports car and avoid driving later at night i get pulled up all the time in a 95 magna that's clean not beaten up. unless you enjoy getting pulled over every time you drive i would avoid a sports car on p plates
