If the car has had a special event in the past then you should definitely wait for the flashback instead of buying it at a showcase discount. We haven’t seen any flashbacks for gauntlet events or special events that include multiple cars, but I’m still waiting on those just in case they become available in flashbacks.

That includes most of the really cool cars in the expert and legend series, but almost all of those cars  appear in multiple series. So there are multiple opportunities to get showcase discounts on them. A while ago I had the goal to unlock all of the cars so I would be able  purchase them if there was a really good sale, but I wanted to do it while maintaining as many showcase discounts as possible. With a little bit of work I was able to figure out an order of progression that allowed me to do just that.

I wrote down all of the cars I had left to unlock and which series they appear in. Then I listed all of the showcases that appeared before the car unlocks in each series. With that info I was able to see where I could skip a showcase in one series to unlock a car because I would get the same showcase later in a different series. The result is essentially what you want, I was able to progress as far as possible while keeping showcases just in case I wanted to use them later.
