I like the ClubSport (and I get the appeal over the R to some). I love GTI's and I like R's. I may indeed love R's soon - I will let you know in dure course.
The GTI is a cult classic and ever will be. There's a lot of talk about the R having no identity, or history/heritage behind it, but this does not happen overnight, or more accurately, over a handful of short years. And though times are different, remember this was once true of the GTI. It has earned it's cult status and I hope the R does too, in time, though granted VW's marketing strategy of flooding the market with über hatches makes this more of a challenge.
As for people 'recognising' an R, I really couldn't care less if they do or don't. It's nice to be complimented on your car, but I buy cars for me, not for a few pleasing comments and admiring glances in the street.
Anyway, congrats on the GT4 wigit (if you take up the build slot), nice to see someone 'going for it'. Life is short, and you never know what's coming next, so enjoy the fruits of your labour. Look forward to seeing your CS pics.
