Just noticed my post on the side!!! I saw a Corgi Lotus Cortina on ebay (by accident as it wasn't listed very well!) and it was listed as an Alan Mann car.
Just checked it over and it's actually the Sir John Whitmore winning 1965 ETCC Cortina. It's also is very good condition with only a couple of scrape marks on the roof. Doesn't quite fit in with my BTCC collection but still a great find. Now I've got to consider whether to keep it (and maybe collect ETCC cars) or to sell it.
And I've also just bought a 1997 Rydell Volvo on ebay
