I agree with Clark. Most of those wouldn't really suit the age of the MK5 GTI, its design is too dated to wear those modern glossy wraps. You can see yourself that the cars in the examples are all less than 10 years old and they have sharp edges in their designs, unlike the MK5, which has very round edges all around.
Although I do like the look of the yellow wrap on the civic, it's the least glossy of the ones you've sent. Google 'fahrenheit gti', that's personally something I'd aim to recreate if you're going for a flashy look for the MK5. The yellow civic wrap reminds me of it.
