To be fair, in defence of the poor old Rocco (which I still love driving), the MK6 Golf has only just been updated to the MK7 a matter of months ago, and when the MK6 was top of the heap, the actual tech offered wasn't much (if anything) different from the Rocco. It's only now the MK7 is out, that not only the Rocco but also the MK6 looks old hat from a technology point of view. Things move on.
I do agree that VW could have had some more imagination over the interior of the Rocco rather than just drop the Eos interior in, but all said an done, it's still a nice place to sit, with very supportive seats, a cracking driving position and a good sporty drive.
To be honest, I think the MK7 and the Audi A3 (both similar tech and built on the MQB technology) have in one fail swoop made most all other cars in this sector (Astra, Focus, 307) look old hat - included the Roc.
Point is, if the Roc was a handsome looking, good to drive, fun car when you purchased it, then the release of any car doesn't diminish that, it's just as I said things move on and the MK7 has raised the bar quite a bit higher this time.
