Last April I got impatient while waiting for M3's to ship so I decided to see what was available in the $60k used MS market. Alas, I bought a beautiful black on black S85 Signature with 18k miles for under $60k. I immediately requested a refund of my M3 reservation...now 7 weeks ago. I called Tesla and the said they were in the process of a 'data center changeover'. Hmm...that didn't sound good. I told them my original reservation was made on a Costco cancelled Amex account...now Visa. They said I'd have to call Amex as I have and was told Amex has no records or history available for closed accounts. Yikes !!! Has anyone had a similar experience?
