Yeah - But how much a litre does that colour match cost???
Whether its Ferrari, Ford, BMW or Skoda, it all costs the same per ltr, and would cost no more in Halfords than any other colour they'd care to mix, providing they have the formulation.
The reason why I mentioned the Ferrari colour, was because on the day I painted my grill, I took 4 or 5 "Reds" off the shelf in my workshop, and sprayed them all onto a test panel, the Ferrari shade matched almost perfectly, thats why I recommend it...
Had Ford Radiant red been any closer, then I would have suggested that instead...
