Any chance you have a link or dealer name?I saw a picture from a Toronto Ford dealer who has an LB and a VB side by side. The VB is ever so slightly lighter.
As an LB V6 owner, I can tell you that they seem indistinguishable when they're apart. Only a side by side comparison allows you to see the difference.
I'd love to see a side by side picture of Grabber Blue and VB.
