>... the engine is one of only three families that spins "backwards" ... Yes and no, I believe there are more than three, here is a fourth one: The FIAT 100 engine[0] (in it's latest incarnation actually 903 cc that was derived from the original FIAT 600 was originally 600, then 750 and 850) was rear mounted on the 850[1] (and was spinning in one direction) the following series of cars (FIAT 127 [2], Autobianchi A112[3]) used the same engine but front mounted and it was spinning in the opposite direction). But most probably there are more examples in lesser known brands around the time they all moved from rear wheel traction to front wheel (roughly end of '60's begin of '70's).
