Lamborghini was originally a tractor manufacturer. The owner, Ferruccio Lamborghini, had an interest in luxury automobiles, especially Ferraris. While doing a routine check, Lamborghini found that the clutch in his Ferrari was broken and he discovered that the car used the same clutch as his tractors. When he asked Enzo Ferrari for a better replacement, Ferrari dismissed him saying he was a tractor maker and did not know anything about race cars. I guess we all know how that turned out.
