I wouldn't say mine is engineered to perfection, you can certainly see where they've saved money. There are bits of trim here and there that don't feel quite as durable or as plush as they were in my Mk5.
However it still does lots of things very well and most other things better than average, so for me it's broad range of talents makes it hard to beat for similar money. It's been around now for about 6 years, yet it's still at the top of its class.
There's still room for improvement (for example the front assist 'auto-restart' feature is rubbish, the rear door cappings are disappointing for a £30k car). But the Mk8 isn't far away and that presents an opportunity to move the hatchback game on further.
The other Golf based VAG cars (Octavia/Leon/A3) are also great all-rounders, just aimed at different clientele. However they maybe aren't perceived as having quite the peerless image of the Golf.
