Mazda USA MSM Production PDF documents initially published by Mazda back in 2005 have been on Mazda-speed.com, Miata.net and many other sites for many years and being published by Mazda themselves, enthusiasts have taken these documents as gospel yet they contain hundreds of errors.

Discrepancies found were:

1) There are over 1,160 build dates that are INCORRECT

2) The cars were NOT actually built in Build # sequence
 

​

1) On the 2004 PDF there are 862 Build dates that are incorrect and on the 2005 list there are 300 Build dates that are incorrect, in all cases of an incorrect date the cars were actually built earlier.

 

For the 2004 models, the PDFs state 61 MSMs were produced for the US market on Jan 28, 2004 the supposed first day of production. However, it was discovered there were 5 Canadian cars produced on Jan 14,2004 BUT their Chassis # fell within the range of the USA cars on the PDF. Build dates for those 61 units were then investigated individually and confirmed all of these vehicles were produce on a different date than listed in the PDF.

 

For the 2005 models, the PDFs state 131 MSMs were produced for the US market on August 18, 2004, the first day of production for the 2005 model year. This seemed suspect as there were never more that 68 cars built on any one day throughout the entire production history. Upon further investigation it was discovered the Build dates for 89 of those units were prior to August 18th beginning with Build # 1 on August 2, 2004.

​

2) The documents are sorted into Build # sequence implying that was the sequence the MSMs were actually built but I can say for certain they were NOT assembled in Build # sequence but in Chassis # Sequence (Note: Last 6 digits of VIN e.g. 4XXXXX)

 

Example 1:

For example Build # 1 has a Chassis #  of 404121 but the lowest Chassis # on the list is 404105 which is Build # 102, supposedly built five days later when it was actually produced the same day. In fact when sorted by Chassis #  sequence there are 10+ cars with a lower Chassis #  than Build# 1 built the same day.

 

Example 2:

Another example, Build # 108 was actually produced on Jan 14, 2004 the first day of production, making it one of the first 15 produced for the USA so why does it have a Build # of 108?

 

Example 3:

Another example, when combined with other known Chassis #s with their confirmed Build dates that fall into the range (e.g. Canada) everything lines up with the Chassis # sequence being the obvious answer.
