My family owned a 1966 Saab 96 (2-stroke 3 cylinder) and that engine was terrible. The engine overheated twice (seizing it, requiring a rebuild and a replacement respectively) -- and then the transmission went -- and that was about 40K miles... We had friends who had a slightly later 96 with a 4-stroke V4 that lasted over 300K miles.
The uRSaab is very pretty, and someone should make a modern version (with a longer rear slope for much better aero).
