People want a Golf because it's more practical and it's a Golf.
People want a Scirocco because it's more stylish and sporty looking.
People want a 3 door Golf because it's in the middle.
I am almost certain that if the Scirocco had the same technical specifications as the Golf R, they would sell about 5 3 door Golfs.
Otherwise where do we stop? I fancy a Touran but a little bit lower. Lets make a special one with a lower roof for people who dont want a Touran. I also want a Polo thats 3 inches longer, and I really fancy a Passat that's like a bit more swoopy. Oh wait

It's pointless. VW keep overproducing cars in a certain market segment and then selling hardly any of the inferior version. You'd think they would learn after the disasterous Golf Plus, the Audi competing Passat W8, the A8 rivalling Pheaton...
But no.
I can't understand why there's such an issue over this. The general populous will see them as two distinct cars.
