While investors may be going on holiday, auto analysts need to stay alert. This afternoon automakers will release vehicle sales for the month of June, so come Wednesday we may open up to a somewhat bleak reminder about the sluggish environment automakers face. Ford’s conference call will be at 1:00pm (eastern,) followed by GM at 2:00pm, and then DaimlerChrysler at 3:30pm.
