Heres my theory

I don't think it is based of inventory as much as it the cards you need. If you have know cars that require FI V8s you will drawing reqularly, but if you have a car that needs them to upgrade they are less likely to appear, if you have 15cars that require FIV8s and you have proed until every upgrade requires at least one you will never drawn unless you get it from an engine box.

The best way to draw any card it not need it for an upgrade.

So try not to pro a car with a midtect until you can take it to lvl 5. in other if lvl 3, 4, and 5, require a total of 4 mids. then stop at lvl 2 and hold of until you have at least 4 midtect to use of that car.

On S class cars don't even get them until you have enough engines to pro them. (because most require engines on all pro lvls.) Same thing for the tech cards.

If you don't belive this theory get abobut 15 cars using V8s and pro up until every upgrade requires a V8.
