Please don't get into the discussion about residuals, thats a ball game that most people don't understand, as they work in % rather than pound notes lost.
I got into an argument many years ago with the mk5 GTI lot saying i would loose more pound notes on a mk5 GTI than we did on the SEAT cupra, but no one could understand it. As they could not grasp the concept of a high % residual of a high purchase price figure is still more pound notes lost than a low % residual of a low purchase price figure.
% residuals is a marketing tool produced by prestige car makes to make people think there product is worth paying extra for.
