Patriotic as I am, i'd have to vote for any of the Norwegian cars. Perhaps Bo's ambulance-white Mk2 Rs1800 is my favorite, also Morley's poison green van. Or maybe that sparkle red (don't remember the model name) with 19'ish rims. Yeah, that has got to be my favorite.
By the way, a really cool pic is from the Rudskogen, Norway Ford track day, a detail of a side window on a beige Esc Mk2 with a RF sticker in it (my car, and I'm a bit proud, hehe).
