three different seats in the e46.....at least to my knowledge. there may be more options.
1. seat with no armrest and seats dont fold down. still will have a metal plate for ski pass. although no way to use since there is no armrest
2. seat with armrest and seats dont fold down still has metal plate behind the armrest.
3. seats that fold down and obviously there is not a ski pass opening in the sheet metal because it is not there with fold down seats.
