Well, I've added to my collection a bit ! Much thanks to DROPPED1 for buying, packaging, and making a trip to the post office to mail me the Playcast and Tomica model. I paid for the shipping and threw some extra in for his trouble and still came out ahead of the game.
BTW, the Playcast model (pics above) with the lights comes with batteries installed and it also makes a little "vvrroomm vvrroomm" sound when the lights come one. LOL But, both models are very nice. Now, I have 5 Z's. The real one and 4 "toys". Also, the little Tomy Z's doors open. I don't think many Hot Wheels cars do that. It's very good quality.
Thanks again, DROPPED1 !
