Fun.
Not something we would EVER see from Top Gear U.K.
(At least in a form that wasn't completely mocking the idea.)
So your suite of mods were: grille block, rear wheel skirts?
I disagree that the factory wheels already look "reasonably aerodynamic".
Looking forward to the results.
Oh, and have fun defending the partial grille block to the uninitiated! (IE. YOU'RE GONNA MELT UR ENGINE!!)
