In bikes, take Miyata, Atala, Schwinn, Fuji, Motebecane, and yes Klein for examples. All produce some high, but many more low end bikes, so none of those brands are truly valuable or collectible. But take manufacturers like Colnago, Pinarello, or Look, and they are always collectible and valuable because they are strictly high end.
