Face lift, yes. Resurfacing the paddock? Yes. But widening the track to F1 standards so that 90% of the corners are flat in anything other than an F1/GP2 car? No thanks. The Craner Curves will become boring. Coppice, Redgate? Who gives a damn. Kerbs the width of a car? Runoff areas the size of Wales? Sure, it'll be 'safer' for club racers, but the challenge and the enjoyment will be ruined.
Most UK circuits - Anglesey, Snetterton, Brands Hatch, Oulton Park, Knockhill, Rockingham (poor example) etc have facilities far in excess of most non-UK circuits. Sure, Combe has no pit garages (nor does Mallory really, or Cadwell), but even there the rest of the facilities are on a par or better than most non-UK circuits.
