The team car sits inside the race, in the convoy, behind the group its riders are in. It moves up when something happens and drops back when it does not. Everything the team does during a bike race is done from that seat.
This puts you in it. You are in the peloton, not watching it, with the sports director working the radio next to you and the feed zone happening around the car.
Morning at the team hotel first, through the race infrastructure, coffee in the paddock. Lunch happens in the car, because the car does not stop. The day closes at the team bus after the finish.
Capacity is very limited and it is priced on application, which is the honest way of saying there are almost no seats.
