In spain the car plates are a sequence of three letters followed by 4 numbers... and currently we reach the "Fxx". In a couple of years we will reach the "MSX", I have to be prepared to buy a new car then!!!!!
Well... not exactly. At the current rate of car matriculation, the first letter takes about two years to change. So I'd say instead that we must wait about 10 to 15 years for having MSX plates.
