My LHS is the same Diecast, Millatary and R/C and 2 old Fujimi Car kits (Merc and a Suzuki Jimny) and a few airfix rally cars.
They don't even buy in car kits.
But am I to blame?. I 99% of my stuff Online from Japan because it's cheaper. I can't justify paying 24 pounds for a kit I can get from Japan delivered @ 14 Pounds max.
