Model Designators

[Walrath]

For the M-Class model years 1998 through 2001 the parts catalogs list the model numbers as 163.154, for years 1999-2001 the numbers are 163.172, and for years 2000-2001 the numbers are 163.174. For a model year 2000 which model numbers are correct?

Doesn't change by year.
163.154 = ML320
163.157 = ML350
163.172 = ML430
163.175 = ML500
163.174 = ML55 AMG

Thank you, Don.
