Since we are on the subject of Prowl, I'll start there. Each of the trio has remolding in some way or another. Prowl's is the lightbar.
They have a very classic Autobot look with the hood chest and window shins, they are one of my favorite car transformers, whether in MP or G1, Classics though, I absolutely loathed. Unfortunately my Prowl is the Commemorative reissue, which means crappy plastic and no chrome on the weapons.
Bluestreak has a remolded roof to remove any trace of the light bar.
The picture of the reissue I had really shows how bad they are vs the originals, and pretty much the chief reason I decided to replace all the reissues in my collection over the next year or so,
Reissue, notice how the "silver" plastic is now a dull translucent gray, and the red you can see through the edges a little as it's slightly translucent as well (ignore the weapons, they are the same original set on both)
He is currently the only one of the trio that I have MIB. I picked the vintage one up off a friend last year for a great deal.
Lastly the third one that came out in 85 instead of 84, Smokescreen. He is the most heavily remolded of the three with a new bumper, roof, and spoiler. He was one of the keepers from one of the huge local scores I got a few years back (I kept one from each score)
In bot mode, he gets white launchers to add to the red, white, and blue colourscheme. He got a nice fresh set of reprolabels to complete him.
Pretty much the Autobot version of the seekers and a staple of any G1 collection.
