A little difficult but the world is a small place , you'll most likely buy them cheaper on UK ebay and get them posted here than you can buy them here for . These are the ones in my collection , I'll try and find the links to some super detailed UK diecast clubman kits (same size as dinky and corgi but have detailed engines , frustrating to assemble I'd say ) .
The following are all scalextric , pretty easy to find used cars here , the sets are harder ...
These are all Dinky , the main diecast maker of clubmans , they turn up occasionally on ebay here but fairly common in the UK .
This is a Japanese manufacturer , "model planning" , they only do tiny models (1:130 scale )
I forgot to get a photo of the springside models HO scale clubman traveller I have , I'll get it next time and post it here . Please ignore the various flash and grime marks on the display cases , haven't cleaned the humidity/crud off after the wet weather (garage gets damp each time we have more than a week of heavy rain) , the models are safe and clean behind the glass
