I do live in a fairly rural part of Dorset but it's not the back of beyond, however none of the local (and when I say local I mean as far afield as 20 miles) newsagents WH Smith included carry these mags, the only one that gets on the shelves round these parts is Complete Kit Car. I have to go into Bournemouth to find both Total Kit Car and Kit Car magazines.
So whilst I have had sight of both the above mags at the recent Classic and Restoration show at the Bath and West Showground the other weekend, sadly I'm looking very unlikely to be able to get copies of either of these mags myself
