saab sonnet information

the Saab 2 stroke engines were 3cyl and the early  cars were made under licence of the german firm DKW.   A DKW 1000 looks just like a Saab92. You had to add oil to the fuel with the early cars, the later ones had oil injection so you didn't have to add any. Just oil to the oil tank. Had a lifetime warranty( the engines) until smog regulations got too tight.(see Trablant) Last year of Import(3 cyl) was 1968?  The V4 engines were of Ford manufacture I worked on the cars during the early 70's. Sonnet V4s were tight to work on. Not alot of room. If you are going to have a web site that makes people think, get your info right.
