No snobbery from me, I like Sapphire Cosworths just as much as 3 Door Cosworths.
Not had an Escort Cosworth yet, one day tho.
"Cosworth" as a hobby has highs and lows, but values are steady for all.
500s rise in value, then 3 Doors, then 2wd Sapphires, then 4wd Sapphires, all pull each other up value wise. Escorts ride somewhere within steadily.
More that get broken keep others on the road, hence values increase.
At least we all share the same "passion".
