Comment Volvo models (Score 4, Funny) 224
Once upon a time, Volvos had a three-digit model number: the first digit was the series, the second the number of cylinders, and the third the number of doors. So you'd know just from the model that the 245 was the lower-end four-cylinder station wagon (the "fifth door").
When they ditched that system (in the '80s?), the first model was something like the 740; their own ad poked fun at themselves, asking "No doors?"
