I for one was making a big stink when people wanted to configure their cars at the time of deposit. All that would have done is put a bunch of orders in for future orphans. At least waiting for configuration until the factory was nearing production time would help weed out those who didn't want to wait.
Now we have people configuring six months or more before delivery, they grip its going to take a long time, and many drop out when they get the call to come in and pay up. I vote for a $1000 deposit at configuration!
