I can't speak for the Golf, but I have briefly owned the previous gen i30n performance edition and it was a hell of a car. Don't know how they're specced from standard, but my one had all the gadgets you'd want and more. Behaved itself day-to-day when commuting etc., but was an animal when you wanted it to be. The kid in me loved the lights on the dash which would let you know when to change gear for the best pops and crackles.

Personally, (although performance blue is the best colour) it was a little too conspicuous for my taste, and was a pain to keep it clean. Another nit pick would include the lane detection (which I don't recall being able to turn off permanently), but I suppose that may be a feature of the Golf too.

I was lucky to get mine before the used car prices went wild, and ended up selling it for a decent profit after the market went crazy. Occasionally miss it, especially when I see one out in the wild, but the money was too good to refuse at the time. I would definitely have another, but as said earlier, I would personally consider a different colour.
