They aren't far from cars. Cars have generations and each generation has distinct models, for market (region), body style, maybe generational steps with facelift, etc. So your "2005 Corolla" is Corolla Gen9 (2000-2007), designated E120/E130 (no idea how they differ), and can be 3-door/5-door hatchbacks, 4-door sedan, station wagon, varying which market you look at.
