After using the web to sell my machines I found italiantrivelle.com and before posting any ads I definitely wanted to check out if it could be a dangerous site, so I've ran a few tests and, it actually come out fine and safe, very good cause I liked since the beginning.
Very good site for certain industry sector like drilling, construction and engineering.
This is the type of site to find informations you wont find anywhere else, besides, you can post your ads to sell your heavy construction machinery worldwide.
