OK. It is a confusing because both chassis/product codes for a series of cars and chassis numbers for individual cars are listed in the Lotus Chassis/Code Names section. However, as is apparent looking through the Model Names section for Lotus, the "commercial" name for a model is very often the chassis code.

When the "commercial" name is the same as the chassis/product code, should it be listed in both sections?

Is the "commercial" name the official name from the mfg or the commonly used name?

Does IMCDB track chassis numbers (or vehicle registration numbers, which is common in the UK) for individual cars?

Once I have a better idea of what info should be there, I can make specific change suggestions.
