Here's my 2000 model Camry wagon with a Card Whiz in it
I can fit most pins in there, even had a couple of widebodies in there in the past (Roller Disco and Stellar Wars)
I havent tried it but i dont think a DMD game with a fold down headbox will fit (i did measure one up once with the head folded down, tape measure said NO lol)
I usually pull the spare tyre and jack out from its compartment under the floor before doing this and put them in beside or behind the game.. no point in tempting fate
