Really good thread this.
My workshop manager done a rally school day over in Wales a few yrs ago, apaerntly the guy who owns the company has and still uses a original 4wd mk4 escort.
I cant remember if it was cossy powered but I think he said it was definately turboed.
Him and my boss have known each other for years and years and knew a few of the Boreham Staff around the RS200 era,
He could probably tell me a fair bit tbh as I have heard a few stories but nothing of much interest.
Will post back up any findings !
