Audatex, a company that tries to answer questions like this one, has come up with a figure for insurance companies trying to calculate the value of a damaged car: with a CAV sticker, a 2005 model Honda Civic hybrid is worth an extra $1,203; a 2006 model is worth an extra $1,509 if it sported the decal. Not a bad deal considering the stickers originally cost just $8. Of course, all 85,000 decals the state issued will expire on January 1, 2011, at which time their value drops to diddly squat. Another thing to consider: an owner who had a CAV-bearing car can now ask for a replacement sticker if that car was totaled. Read more in the Audatex PDF here (HOV story is on pages 12-13).
