I too bought in Nov 2017 and not surprisingly having the exact same problems everyone else is having. I thought I did my research before hand, but none of the BBB info or this site came to the top of my searches until afterwards. I visited Steve and saw his business first hand. He was a pleasant man to talk too and I could tell he was excited about his work.
However, after I gave him my deposit, I haven't heard anything at all. I've tried calling, emailing and written letters. No response. None what so ever.
I have no idea where I am on his current list.
You are likely to be on the bottom of a VERY VERY long list.
Not much has been said in the past 2 years but if you read through this list you'll see that SAS has not delivered a completed car in over 3 years. I'd return immediately and get your money back.
