Is there a website that will show by % how many vehicles out of total sold(i.e. for that month) had which options? For example, for October '07 how many Mercedes S550's came with navigation or whatever option, etc... I have found websites with sales figures but nothing that breaks down what % had which options.

 

No website I am aware of. That is info a dealer can maybe get for you or maybe call a carmakers 1800 csr service #
