I remember as a kid, I spent hours upon hours drawing the Ecto-1A in crayon.

Lots more fun than the "boring" old original version. HAZARD TAPE!
Me and my best friend were f*cking
obsessed with Ghostbusters back then, man. We had all the role-play toys, the Proton Packs, the Slime Blowers, literally every single damn thing. I even got a super-awesome official Ghostbusters II jumpsuit uniform, the Christmas after the movie came out... which I outgrew in like less than a year. But it was still awesome for that little while that it fit! But yeah, we played that sh*t hard for a long, long while.
We each had a "junker" car in our respective backyard, so we'd also often clean them up, slap a bunch of homemade decals on them and spiffy 'em up to look like the Ecto-1 (or 1A). As close as old beater station wagons covered in kids' construction projects could get, anyways.
At one point, around '88-ish, we were kinda wondering if we were a little too obsessed, doing all that kinda stuff to that degree. But then we found the NOW Comics "Real Ghostbusters" comic book, and every issue they had a gallery of photos kids sent in of themselves doing all that kinda stuff, and stuff way more elaborate, even. So then we felt okay again.

"Okay, we stuck Ghostbusters decals on the old station wagon out back and pretended to drive around busting ghosts, but at least we're not that kid who built a kid-size seatable Ecto-1 out of Legos."
Fun times. I admit, when I go to Wal-Mart and see the new roleplay toys they have out for the new movie, I'm tempted to buy them just because 6-year old me would absolutely
have to have them. But so far, I haven't. They do look pretty cool, though. I like the modular Neutrona Wand gimmick.
Also tempted to pick up the new toy Ecto-1, kinda. But I literally just got the "Plasma Series" Ecto-1 that's all deluxe and sh*t, so part of me feels like getting this one would be redundant. It's only like $25, though, so maybe.
