When can I buy a Rolls-Royce Spectre?

I'm eagerly anticipating the release of the Rolls-Royce Spectre and I'm wondering, when exactly can I expect to be able to purchase one? Is there a specific date or timeframe that has been announced by the company for its availability? I'm also curious about any pre-ordering options that may be available and whether there are any expected delays in production that could potentially impact the delivery date. Additionally, I'm interested in knowing if there are any financial considerations or requirements that I should be aware of before making such a significant purchase.
