How dare you criticise AutoTrader when loads of people are fine with them. Why don't you take it up with them before ruining their reputation by posting on here? How would you feel if AutoTrader was your company? Don't you realise that this isn't good, this thread will stay here and when people Google autotrader (not that any MLR user has heard of Google) they can find this thread?
It seems your bizarre text is where targeted ads normally go so maybe they were testing something at the time and a test ad slipped through they net? Either way it seems to be working fine now.
