When I cleared out my late Step Fathers Garage (about 18 years ago now), I had 3 boxes, Keep , Skip, eBay, needless to say most went in the Skip box, I had come across some old Ford Glossy Sales Brochures from Trimoco Chelmsford, an RS Dealer, they where still wrapped in a plastic Tesco bag, from memory there was about 4 on the New Cortina (Mk2), various models, 2 or 3 on the Granada and the Coupe, a couple on the Escort, one on the Mexico and one on the RS1600, they all went into the Keep Box, followed a few mins later moved to the Skip Box.
Tea Break time still pondering, moved them to the eBay Box mainly thinking someone might like those somewhere, eventually I put them on eBay and was dump struck what I got for them with a 99p Start, the Cortina ones went for around 20 quid, the Granda's about the same, the Granada Coupe went for around 60, the Escort basic ones didn't sell, but the Mexico went for around 100+ and the RS1600 just under 200 quid.
Just wish I had more, bearing in mind that was around 18 years ago would they have been worth much more today?
