Was just reading Jalopnik article about F1 test days, it mentioned that Jenson Button drove a Clio V6 to the track when he was driving for Renault. Wonder where that car is now?
Jenson Buttons car was a Mars Red phase 1 v6, number #199 registration - HT51 KNG.
Last time i saw it, it had a supercharger fitted and was having a few engine issues. Hopefully it has been sorted out and is still going.
