I doubt that anyone reading this is unaware of big john's unique record as being both FI WDC and GP1 world champion
and those who also follow GP1 will be aware that casey stoner has announced his retirement at age 26
those who watched him secure the GP1 championship on a ducato will know that he has a most extraordinary sensitive touch on these 250hp ,300kph machines , and personally I have no doubt he could make the switch to 4 wheels
what an addition he would be to F1
incidentally , enzo ferrari is on record as saying the biggest mistake he made in his career was losing surtees services
