It's because Subaru are a bunch of Satan-worshipping occult pagans. think about it: all those pentagramish stars in their logo... and then the letter B is the 2nd letter of the alphabet. There's two 2's and a B (22B) so there's 3 figures altogether. 2x3=6, right? And if you take it a step further, you could just say: "aw hell, let me multiply all of those 2's by 3". What do you get then? 666. Then if you think about it, whenever you see a paganish hippy type with tons of bumper stickers on the back of their car that say things like "all who wander are not lost' or "My other car is a bicycle" what are they driving?? Either a VW bug or bus, a Subie wagon, or (less often) a Volvo, simply cuz Volvos last forever. Think about it.
