The Delta is my pick of the Lancia line up. That Austin 1300 is a bonefide classic now. The Lotus Excel is a car I loved when new but just doesn't grab me these days. Has a Metro's time come?
Excellent on track photos - a long lens and a monopod? While I love the clusters of cars that Galaxy from the rear really works.
As well as getting up on banks if you know where to look at Brands Hatch they have "windows" through the mesh for photographers. Ian Conway has some favourite spots where with some low steps he can see over the mesh. For myself, only bothered to carry a pocket camera, I love the Grand Prix loop out in the woods where you stand above the track and really quite close on some corners.
A long lens but no monopod. With enough zoom you can frame a shot through the holes in the fence although the autofocus on my camera does occasionally focus in on said fence at just the wrong moment when a particularly nice machine comes into view... I did walk out to part of the GP circuit but I must do it properly next time.
As somebody who used to own an MG Metro not that long ago, I can confirm that there is a thriving club with lots of passionate owners although cars are still relatively cheap. The car in the picture is the MG Turbo and these are very rare now.
