I hear what you are saying Pete but it does not hurt to keep knocking on the door , might get a result one day .
Lets face it politicians are more desperate for friends than Smallcox

and the classic car brigade are big in the UK.
Sounds like you guys in Oz get a pretty raw deal running old motors.
My '72 500L and '81 126 cost £45 each for the MOT test, they are both on the same fully comp unlimited mileage insurance which cost just over £140 , being '72 the Fiat 500 is zero rated for road tax but I was surprised that the 126 was £155 for the year. More than our 2 modern cars as it is based on emissions.
