The new process here in the U.S. (assume its the same for you now as we'll?), when you hit the "Done/Finalize" button it confirms your commitment to purchase the car. But note, you then have a two week grace period to both make any final changes to your design, and/or back out - and still get your reservation money back. Though you will need to contact someone to do so.
When you hit the Done/Finalize button, that starts a two week clock. If you do nothing, in two weeks your configuration will automatically go in to production, and at that point you will not be able to get a refund on your reservation funds. Remember, during this two week time frame, you can still make changes to your configuration.
After two weeks, once your car goes into production, you will get a new button that shows you service and warranty options. You are not required to add these at time of final purchase. They can be added later if desired. See the website for these options and pricing for you.
After another week to two, you'll get the Delivery button, which begins the scheduling process for the car. For Europe I have no idea how long or how this phase of the process works. Over here, it's then just 3 to 4 more weeks for arrival. At this point, you're well on your way to receiving a your car.
After the delivery scheduling, anywhere from a day to a week, you get final a button for final arrangements to purchase/fund the remaining amount due on the car. This final amount transfers on the arrival of your car.
NOTE, this is the current model for U.S. residents, I'm not sure if it differs for those of you across the pond.
@ Yobigd20, the process here in the states has since changed from what you're describing. That change went out at the start of April I believe. It may be still in effect for Europe, but none of here know for certain.
