Exactly, like I said, many geniuses here think designing a car from scratch is so cheap and easy. Heck, even changing a hatchback into a sedan isn't that straightforward.
They need to take a look at the world and see the reality - manufacturers are running out of ideas so some similarities are inevitable. Although I do wish that they kept the Savvy's front or at least improved it while still retaining a Proton identity. Maybe a Satria Neo kinda front look?

Honda added 2 doors to their Integra DC5 to become the Civic.

Honda added an ass to their Jazz to become the City.

Toyota added an ass to their Yaris (and with less features) to become the Vios.

Nissan added an ass to their Latio Sport to become the Latio sedan.

Chevrolet (Daewoo actually) added an ass to their Aveo to become the Aveo notchback.

Best one of all: Hyundai Sonata. The previous one looked like a Benz's front mated with a Jaguar's rear, while the current one looks so much like the pre-facelift Accord. Looking good at the same time.

Hell, the racer boys' favourite Subaru (I have nothing against Subaru, in fact I love it too)... they now have their own version of the Boon/Passo/Myvi called the Subaru Justy. Copycat right?

But no, they are not copycats. They are not hopeless. Why? Because they are foreign. So the geniuses here seem to think.
