Other than world domination do you think it's autotraders aim to become the new cap ? Given we have glasses, parkers and what car pricing of which everyone seems to give some form of random figure who's to say who is right.
i'm not sure how autotrader come to their pricing given I've seen it both under and over cap figures, it seems to suggest the part ex price is the average trade price, how it works this out I have no idea. I can see that the average retail price they can work out given than most cars are listed on their site. The trouble is while 50 dealers could stop using them it's not going to make a difference because main franchises will still use autotrader even though they have their own websites and approved used programs.
it needs someone to take on Autotrader but given that some have tried and failed it's going to take deep pockets and lots of marketing, even then they still have brand presence. It needs someone like eBay or Amazon to take them on, however would someone like Amazon be any better ? They seem to screw the middleman too.
