If it was any cars then it would be called Cars and Coffee not Clios and Coffee...
It's a Clio specific event im running due to the lack of Renaultsport/Clio specific events running this year with CSOC Weekender and FCS both not being on. Pretty much all the spots have now been filled just a few left.
I get where you are coming from, but this forum probably has more members who no longer own clios but stick around for the social side of things.
If you opened it up to other cars being allowed on the rollers then you'll be sure to get an even better turn out and more variety of cars on the rollers.
I went to a rolling road day before and it was mostly clios, boring as hell once you've watched one run you've seen them all, everyone was more interested in seeing the other cars on the rollers after all the clios had ran.
That's just my opinion anyway. I'd be interested in coming and running the fiesta to see what it's producing. Nevermind though
