I had the rep ring me today trying to get me to sign up with Gumtree as I'm already with Ebay, he probably wishes that he hadn't now. I let him get a few lines in then I asked him why would I want to advertise with their 3 different sites Ebay/Gumtree/Motors, his response was that people tend to look on 3 different sites when buying a car and if they see my cars on all 3 sites then that will assure the customer that I'm a bone fide motor dealer.
I mentioned my concerns about paying the same company three times for doing the same thing and that I thought they had a conflict of interests, and that I tried Gumtree and Motors before and they were rubbish so why would I want to advertise with them now.
I also said that I thought that Ebay had gone off the boil and this seemed to happen when they took on Gumtree, which is a shame as I thought they were making real headway against Autotrader. He couldn't really answer my points, and I mentioned I'd be rethinking Ebay when it comes around for renewal in May.
So it would be interesting to see how you get on.
