Why it matters
The Monster was a one-off experiment, a Saab 93 stripped of weight and fitted with two three-cylinder two-stroke engines. It was never raced and the tests were not repeated.
How rare is it?
Six separate kinds of rarity – never combined into one number.
Each kind of rarity is rated separately and never combined.

History
Built in 1959 as a lightweight Saab 93 with a plastic bonnet and two 748 cc three-cylinder two-stroke engines, the Monster has a combined swept volume of almost 1.5 litres. At the Satenas airfield Saab engineers timed it at 196 km/h, but the run was made in one direction only and without independent inspectors. At the Gelleraasen circuit near Karlskoga it proved hard to corner and the power was too much for a pinion in the transmission.
Autocar adds that Saab could not find a competition series that would accept it, so it never raced, and that the nickname Monstret is Swedish for monster. It is now in the Saab Museum at Trollhattan.
