Apparently, the code is such
- One letter, and one number, that's the base model
- Maybe a 2nd number if there's multiple body types
-
- 0 for 3 doors
-
- 1 for 5 doors
-
- 2 for SW/Break
-
- 3 for 4 doors
-
- 4 for leisure/minivan/big utility
-
- 5 for Coupe
-
- 6 for Coupe/Cabriolet (convertible)
-
- 7 for Cabriolet (convertible)
-
- 8 for Monospace/Minispace
-
- 9 for (small) utility
Restyling often (but not always) only increment the (first) number by 1
