A few days ago I found on a blog a picture of a car with MSN Messenger stickers on it. I posted the picture on my MSN Space and in a short time the mystery was solved. Thanks to all who contributed (especially Saras).
The picture was taken in Israel by Netanel Jacobsson who used to work for ICQ/AOL and now is working at Maxthon. So if you live in Israel you can buy a Chevrolet Aveo and get a discount if you agree to apply a few MSN stickers. Go to www.chevrolet.msn.co.il and try it yourself.
