The colours available will all be available after. Not sure how many different colours actually. The first edition was the so called launch edition, the second was launch 2, not sure about the difference. I believe both were normal or comfort, so leather inside and not too much carbon outside. The third edition was called performance. Not all colours are available for all editions but most are. All colours are new. There were no bucket seats available i believe but not sure, not for the first 400 i mean. Mso options not available for this launch. Probably ends autumn/winter regarding delivery before 401 is delivered. Please note most of this information is from mclaren personel trying to answer all the storm of questions. They had great 3d screens and even vr for illustration.
I ordered it yes like all i think, and the most i liked was the overall improvement on all levels, and in regard to the looks it is overwhelming so i think i am going with a dark colour.
