If you're only at level 400, you have a LONG way to go before materials become obsolete.

I'm level 800+, and saving up materials for the Idol of Wealth series of decorations, while periodically adding more tracks. It's taken a couple months of saving mats just to get to 100 mil, which means I'm a little more than half way there.......(it's getting close to the point where the cost of new tracks aren't worth the expense of 30+mil in materials).
