Interoperability with other products

As an independent data provider, I do not guarantee interoperability of my databases with other products available online. Actually there is no interoperability between my own car databases, each one being developed independently from different source.

If you check major automobile websites like,,,,, eBay, TecDoc, etc, you will see lots of hierarchy or spelling differences, because each one built their database independently. Matching car names between 2 databases is a coincidence rather than a rule.

Most common conflicts are at BMW and Mercedes, some show model “BMW 3-Series saloon” with trim/variant “320i”, others shows model “320i” with trim/variant “saloon, touring, coupe, cabrio”, etc, others shows model simply “3-Series” with trim/variant “320i saloon”, and some of those who show 3-Series as model put M3 as separate model instead of a trim/variant under 3-Series.

In the original line of products started in 2003 for Europe: Car Models List, Car Models Encyclopedia, Car Models Database, Car Models & Engines Database, over years I done numerous changes to make model hierarchy as efficient is possible based on parts compatibility, so M and AMG models are not listed separately than their base model. If you find differences between mine and other databases, do not claim that my database is wrong and yours is correct, because NOBODY is correct in relation with others. Even if I adapt my database to match your data, tomorrow someone else may attempt to combine my database with some other data and complain again about differences.

An example of argue with an American customer is whenever WRX is a trim of Subaru Impreza or a separate model. Edmunds website itself list same car in 3 different ways: trim WRX under Impreza model for 2002-2012, then Impreza WRX as model for 2013-2014, then WRX without Impreza badge for 2015-present. This because in the recent years Subaru USA is marketing WRX more individually. And there are thousands of such conflicts.
