Hey mate, cars cming allong nicely.
Wish I had the time and money to progress this fast haha.
As for the grey:
If you want to be turning heads a dull grey isn't the best choice. It rectracts from the car, makes everything else slightly dull.
You should be goign for something lighter, or make that shade metallic.
my 2 cents ;]
Edit: The twin tips, is awesome, I want some!
