I haven't ever tried this but the centre of rotation will be somewhere along the rear axle.  Most modern vehicles have differential gearing which allow one set of wheels to rotate faster than the other, depending on the direction of the turn.  

Oddly enough, there's a new US built "muscle" car with a fixed rear axle, which, IMO, is stone age engineering.  But I digress

I would guess that on a left turn, the centre of rotation will be near to, or at, the left rear wheel, and near to, or at the right rear wheel on right turns.
