I am looking to acquire or license a reference database for
aftermarket car parts.  The database would contain all the various car
models and details for replacement parts.  I am particularly
interested in oil filter requirements.  An example would be NAPA auto
parts (www.napaonline.com).  You can visit that site, select 'filters'
under 'replacement parts' and then choose the model year and car model
and site will provide you a reference to the appropriate oil filter to
purchase.  This data is available to retail auto parts suppliers and
garages.  I am looking to use this on a website.
