There was not an issue when I ordered my car, but then again I did not order the Recaros. It may have just been random server issues. So far no one else (at least here) has complained about the ordering program itself.
To be honest, from a purely selfish standpoint I hope the Recaros are among the backlog since I figured at least half the AMG purchases had those which would cut out a lot of the people in front of me.
They were finally able to add seats. I wonder if the number exceeds their inventory, the system will not allow them to add? My order is due, way out until April. I feel this car is quite low production or maybe we will see many more when they market the 4matic 250's at that time?
