did mine over 2 years ago,think was the longest i have spent on a model.I used a solido Focus rally car,had a bodyshop paint it,filled the roof holes in,i used the solido base plate then grafted a ut Escort cossie interior into it,pain in the arse that was,trimming the dash down as the doors wouldn't shut i used a sierra cossie engine mounted transversly.Interior i tried to replicate as best i could,i even used black felt for roof lining & the A & B pillars.
