Re: This is weird...
Actually your VIN makes sense. I just think the list Ron sourced is somewhat incomplete and a 5th digit of "M" should be listed as M Coupe (99-00) just like "N" is as M Coupe (01-02).
As a mentioned in a previous post the list is also missing "M" as a valid 3rd digit value. My car, a 2002 US-spec M Coupe, is "5UMCN934...".
As fo the ETK showing your car as a "ZA-spec" I'm not surprised. The exported (from North America perspective) M Coupes all seem to have "LB5xxxx" series numbers and it probably wouldn't take much for the database referencing VINs to specification to get out of whack.
