This is the 2003-ish Johan reissue, I've had it in my stash for almost a decade. What's sad is I did the chassis a couple of years ago (I added the AMT '62 Thunderbird custom wheels and tires), and the bodywork a little later, but it pretty much sat all that time. It only took a few hours to actually build.
I decided to do it as a slammer- even with the detailing decals, that shallow interior was nothing to write home about, and the thick green glass didn't help matters. I also used the police siren and decals... now it kind of occurs to me that "slammer" is also slang for a jail cell, and this is a cop car. Seems fitting.
