The 'focus' you talk of is a spacefamed chassis, running a 'liner engine and box - Only thing ford about this is the shell they place over it, and thats a copy at that.
The swedish Escort your vid is about was a complete one-off and cost too much to do again and the creators left it at that. Due to popular demand they have decided to give it another go.
The new reyland was a similar story but isbeing built, there arny many details but its got a better rollcage so it doesnt happen again and its also out to set a new record for Reyland.
For the past 10 or so years Reyland has built mental cars from the Series1 Cossie, Mondeo ZT and the latest Esc cossies. Keep ya eyes peeled cos I might post some interesting stuff up if I can be bothered
