Chris Evans’ CarFest North. Just as big as CarFest South

Chris Evans’ second petrolhead extravaganza – CarFest North at Cholmondeley Castle – has been as big a success as CarFest South. It may be a new petrolhead show on the calendar, but Chris Evans’ CarFest Shows have been a real success, not just for visitors but for the BBC’s Children in Need charity. This last weekend saw CarFest North try and follow in the footsteps of last month’s CarFest South, which it appears to have done in style, pushing the amount raised for Children in Need up to £800k from both CarFest events.

There's a natural lull in the model cycle after a ballistic 2007, and we'll have to wait until later in the year to see another new model, rumoured to be a concept car for a future model line.
