WARNING: Their site is actively getting harvested for e-mail adresses!
So, I advertised my vehicle and nearly every sales lead I received from classiccars.com was a bot harvesting my e-mail address. As it was important to respond to the sales leads, I did so but I also immediately noticed a sharp increase in spam mail. Almost exclusively American spam mail. Only one sales lead came back with a response and that responder had absolutely NO interest in buying the vehicle. There are other classic vehicle websites out there. Rather try them out.
