For most of Panini's blasters you don't get much. Torque and Absolute Racing have only one pack per box. Select has three. Donruss has 6 per blaster and has an actual, collectible set. Torque and Absolute Racing both have sets, but you get only two or three per box, not really collectible. Both are 100 cards in the base set. Select is decent but is all chrome- think of it as Finest for NASCAR.
Donruss came out first this year, so you might not be able to find it at retail easily anymore. (I did a hobby box in March 2017, and it wasn't brand new) But if you want to build a set, that't the one...although it will probably frustrate you. The first 30 something cards are short printed, and the last 30something are also short printed. What are normally inserts in the other sports, like (Whatever) Kings...in basketball Rebound Kings is an insert. In NASCAR Race Kings is a short printed part of the base set.
There is also National Treasures which is $400 for 5 cards, but it's really not a set. It's a memorabilia delivery system. It's the only Panini NASCAR set that does not go to retail.
Panini considers Donruss to be the flagship set, by the way.
Select is sort of buildable as a set- the first 100 cards are normal printed. #101-140 are short printed enough that I've done three blasters of the set, and got one of them out of all three blasters combined. I don't know if it's better in hobby, because I can't afford that anymore...and if I did I would probably buy hockey instead these days anyway.
Although this may sound negative, I actually do like what Panini is doing with NASCAR. They really don't care about set collectors, and seem to go out of their way to make it impossible to collect that way, but they actually put out cards of cars, which is something Press Pass could never figure out should be done.
Maxx went out of business in mid-1996. Press Pass had the exclusive license from 2001-2015, when they went out of buisness. They put themselves out, by the way, by focusing solely on high end sets and getting rid of the sets that got them a fan base in the first place. Maxx was my favorite NASCAR brand, by the way. If you're interested, I have thousands of NASCAR cards available to trade, about double what I have listed...my tradelist has not had anything new added since January 2015.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
