I hope you are all doing good these times!!
I found this add for a Costello GT not listed in the "cars" area:
Best wishes to you all and a better 2023

Hi Guido - this yellow GT was the one I helped rescue from a garage a couple of years ago. It's listed in the pages but was still green in those photos. Now resprayed to its original colour and had some extensive recommissioning.
