be careful don't want it to look tacky! What I did was get the proper silver fascia and also colour coded the surrounds of my HU and screen in the similar silver colour like the dash so that it blends in better as they were just boring black. I found that the smoke grey metallic is the best match don't use alluminium as its to light. Looks quite good and a proffessional finish, but still won't spray above MFD and speedo in that colour as its not 100% match but very similar in the dark If anyone knows yet of the exact 100% colour match for the console colour please let me know, or I will simply paint all the existing dash this colour to match up.
My flatmate also has a 2002 corsa but his is the early 2002 model where mine is the later part. My interior silver is a lot brighter than his is, I think vauxhall call it matt chrome? The facia I bought would match his silver, well it was either that or black!
