I'd like to design a database that will store automotive performance data so that the user can compare performance results between various automotive makes.

The front end will probably be set up with individual makes grouped together with bullets that the user would select.

For example: Audi, BMW....etc.....and then individual models under the make category would be listed with bullets for the user to select.

The front end will utilize PHP with a MySQL database.

What would be the best way of setting up the database in terms of table structure, primary keys, etc.?
