I once had the Marcos detailed (by a chap called Paul - Shine On) took about 16-18hrs just on the paint. I am not exaggerating when I say this, it was a completely new car, almost unrecogniseable.
If your car is looking a bit tired, a decent detail makes it totally new. And if you think it's not looking tired, you are probably wrong and it does! I didn't even know what colour my car actually should have been as it didn't even look like that after it was painted!
That is lovely work on the 360, makes a special car even more so.
