Need to connect our website to another customers webiste so whenever they post a car on their webiste it will be posted on ours, if they remove their car it will be removed on ours. Observe that it wont only be connected to one website it will be done many pleanty, but i belive if we connect to one once the rest will be similar and more easy? Please type "[login to view URL]" So i know that you have read full.
Also of course we have approval from the other website owner to do this
