Thats one hellva collection you have.
I sold a mint boxed ut imp blue cossie and yaco cossie 5 years ago for £50!!!
Regretted it ever since but did pick up a boxed silver ut wrc escos from a toy fair 2 years ago for £20 box isnt mint but well happy with that.
Would love more but can"t afford them but have a nice lot of 1.43 escorts so happy with them but there still boxed in the loft need a display case..
