They are genuine VW parts, hence the price and the likelyhood that reversing lights won't be any better (Golf R owners have the same complaints about it as the rest of us). I could buy a genuine reversing camera kit for ~$600 but installation is much trickier.
I got my car second hand, t. - much cheaper than what the car would cost brand new. A brand new at my spec would've cost around $40,000AUD, whereas the Golf R is getting around for $75,000. I'm not a big fan of loans or credit cards, so I bought mine outright. For me it's not about the price, it's about justifying it. The Premium Bluetooth kit set me back about $400, the MDI about $300, and the sat/nav infotainment system about $1200, but for the additional features it was easy to convince myself that they were worth it.
Unsurprisingly, most of you guys like it, which is good. I think the plan will be to wait a couple of months to see how 'common' the LEDs become on the other Golfs, as I think they're now available as options for the lower models starting from the MY11 range. If they're still fairly exclusive then I'll go for them to renew the look of the car. :)
The R32 was a 3.2 litre V6, whereas the Golf R has a 2.0 litre TSI engine, for better economy, but still a bit more powerful. The MK6 Interior is a great place to be in as well compared to the MK5.
