I saw one of these at the NYC Auto Show, back in the late 60's. I loved it, but I was still in my mid-teens. For some reason, I thought that some/all had two-stroke engines. I know that SAAB did use those. Anyway, yours are great, and I'm glad you've gotten so much enjoyment and reliability from them. Thanks for a very fine and informative article.
In the very competitive autocrossing days of the early 70s in DC, Schwing Motors, a Saab dealer in DC trailered in a monster FTD Sonett driven by a very good driver, John Ames. The gearing allowed him into 4th gear when most of us spent time in 2nd or 3rd as I did in the Dick Freeman built FTD Mini. That Sonett never had the hood open, so we never saw an induction system, but the fat slicks on all 4 corners let you know it was something special. Its had more power than the 1293 cc Mini with 2 Webbers 40s and a cross flow head and it weighed only about 200 pounds more. Does anyone know where that Sonett is today?
