I'm also waiting for a test drive, but I'd love to poke around in the design studio already... I don't understand the logic in only allowing people in X at a time... not everyone who plays with the design studio is going to click 'order' at the same time...
There are lots of other reasons for staggering access to the Design Studio, such as:
- there are still more changes to come to the options in the design studio, reduces the number of people confirming old options
- their queue is completely full for the next few months
- no point in having someone confirm their order and have to wait an excessively long period of time (e.g. people would be complaining they ordered 3 months ago and still no VIN)
