Enzo Ferrari refused to sell Mr.Lamborghini a car at one point so Lamborghini took the snub and made his own super cars.Of course neither Lamborghini Tractori nor Lamborghini Automobli are owned by anyone with the Lamborghini name anymore.
Enzo also subbed Ford acting like he was going to sign a production deal with Ford Motor he then refused to the deal out of the blue(likely his plan all along) Ford fought back which is how the GT40 was born to stick it back to Ferrari and it did winning 1st,2nd and 3rd place at the 1966 Le Mans 24 hour while no Ferraris made it into the top 15 ouch.
