I have seen many times for part sourcing to look for 2003 SLK32 AMG parts. Why the 2003 and not 2004? Are some differences with the 2004?

 

there are no differences between a 2003 and 2004 SLK32 that I am aware of. The only difference between the 2002 (SLK32) and 03-04 is that some (most?) 2002 SLK32s had the "bolt-on" style axles. Few 03s made it here, less 04s

these are the USA production numbers
2002 1182
2003 562
2004 312

 

latemodel21, Thanks for clarifying the facts on the SLK32 AMG for me.
