Bimmer vs Beemer

http://www.bmwccbc.org/misc/tech-and-trivia/bimmer.html
Bimmer - proper accepted slang for BMW cars. Most people don't know this.
Beamer/Beemer - proper accepted slang for BMW motorcycles. You will hear this term used incorrectly by many people.

p/s: tapi, aku lagi suka guna slang beemer atau bmer sebab ramai yg guna walaupun salah... heher
