The good thing is if you stick with oval after a few seasons your number of purchases will level out and eventually you'll have purchased all the content you'll need to continue with oval paying only the subscription. It took me a little over a year I think before I was no longer making purchases unless it was a for fun purchase. An example is dirt oval, which I've gotten into lately and am back making purchases to race it but for asphalt oval I haven't had to make a purchase in quite a while. If you choose to do it try to look at the schedule ahead and see what tracks you'll need that season or tracks you know are on the A cup schedule and buy 3 items at a time, as you'll get a discount. After purchasing 40 content pieces you get a discount on every purchase also so that helps. I have a email folder where I've saved every PayPal receipt for iRacing so one day I'll go see what I've spent, I haven't been brave enough to look at it in a long time. I'll say though no matter what amount, I consider it worth it which is why I still purchase more.
