Verdict on this box:
I just finished the last pack, and the set of 300 cards is actually quite decent. The photos are nice, featuring the classic Winston Cup and BGN from '93.
However, I noticed that each pack you open strangely contains identical cards from one pack to the next. Let me explain:
if you pull Earnhardt, Jarrett, and Waltrip consecutively, for example, if you come across another pack with Earnhardt, you're 100% guaranteed to get Jarrett and Waltrip behind him. It seems like the machine at the factory arranges the cards in a very precise order within the packs.
Personally, in my box, I found the same order in every pack, with the sequence of drivers, team leaders, etc. However, I didn't receive any inserts!

In conclusion, if you're a NASCAR fan, go for it; it's a very cool set to have. However, it's very similar to the '93 box in chromium. While not exactly the same cards, there are some identical ones in both sets. I must emphasize that the '93 chromium set is not 100% identical.
