yea, it would only take one table. It depends on what the car ids are, if they are like a10s5 then you cant do it, because auto increments can only be INTs...No, you cant have all the ones above 326 drop down one, although it would be very easy to create a php code to do that for you. make it a function and a form on a page so you just enter a number and it automatically drops everything down one..
