Even thought I'm chopping in for an R, the GTI is an amazing car. Performance pack is so worth it, not only for resale but for the handling, calipers etc. If you can afford it, I would also say the DNS Pro is excellent, even though I don't have it (wife has it on her GTD). Dynaudio is also great value for money. I also prefer the 19" Santiagos, but that's only because the standard 18's look like the Monza's off the Mk 5 and 6, of which I had both, so I fancied a change alloys wise. The standards still look the nuts.
Consumption wise I get less than some of the others on here (on average 31-32) but I do have a lead foot so that
may be something to do with it.
I love driving it every day even now after a year. It's a great car. I still get looks now when driving around town, it stands out without being too flashy
