I did exactly the same and picked up a demo car. I’ve had it for 3 months and made several changes to my order.I ordered mine in July 21 with an expected delivery date of 2nd quarter 2022. Also learnt that demand is double to what was expected. So I couldn't wait and decided to purchase a 1 year old Taycan with the intention to part-ex this in against the new one. With demand being high I don't expect too much loss on the vehicle and no more than what I would lose on a new car over the same period. Also, with owning the vehicle for 2 months I will tweak my order spec.
