I have ordered one but my dealer couldn’t answer all my questions. I just found this website and hope to compare information. Is Cadillac limiting the production to just 250 or was that just the initial registration number? I used a build sheet to order, but did not receive a build brochure. Is this something you could share? Also, the build sheet did not offer magnesium wheels. I ordered the Q61 satin graphite, but would be interested in any info on the Mg.
