Looks wicked, I'd love that, leave it as it, keep it clean, save for a 1.8 zetec on carbs .

You could upgrade the brakes to cosworth, polybushes, 5 speed box with LSD (maybe a 1.1 box from a fiesta mk3 and s1 diff for acceleration), 16i roll bar etc. Just leave the looks alone

Edit: out of interest if you don't mind, how much is your insurance, who you with, what's declared etc? Cheers
