your experience is basically what happened with my factory order Mazda Miata haha. I ordered it and didn't get a notice it was ready until 6 months later when it arrived on the boat from Japan. One of my friends had a factory order Porsche and that took about 1 year from order to build, not including waiting for a dealer allocation to get the build spot. So some perspective for other with a high volume cheap brand (Mazda) and a luxury high end (Porsche). I think waiting for a custom order car to show up by the end of every quarter is acceptable to me
