I have seen the model launch schedule, showing production start, embargo end, advertising campaign, wholesale and retail dates ...
Can i ask how you know this lol? That sort of information is provided to the dealer network under the pretence that it's confidential and only really for internal use and to give customers an approx of when new models will launch.
That would be a tad silly wouldn't it? Why would he dip the source of the information in sh*t? Just nod and agree.
