Creating a relationship between taxonomy lists
There are other ways to do this, in Drupal there are always other ways.  But before you try to implement a solution, ask the question 'what will I want to do with the information besides a direct look up' of say Corvette, year, motor size.  As soon as you find something else you want to include, say various models in a year - coupe, convertible, etc.- or information on colors, performance, displacement, maximum this and that,  you will find yourself redesigning that taxonomy again.  Drupal is a Content Management System and is entirely contained in the database.  Instead of laying out a taxonomy, work on the design of your database.  When you have a good structure for that, start creating fields and use the Views module to generate the content in whatever form you desire. Views is basically a UI for database queries with some great Drupal flexibility for assembling and displaying the content.  

I hope this is helpful. By the way, Drupal is complicated.  It is very powerful and has a bit of a learning curve.  That's why this site has been successful.  Three months ago, I couldn't even spell Drupal, now I can :)
