Yes, they did. I can see a release in the future of an original Metroliner, most (maybe all except for stamping the proper holes in the floor) of the tooling is already done, even a power truck using, maybe, the one used in the Budd car.
That would be pretty cool! As my collection evolves, my current metroliners look silly. Over the years, I have unloaded most of my non-scale items to eBay, but my metroliners and E60s remain. The E60s weren't too bad once I painted the roofs (and they pull with the might of ten men), but those metroliners need a modern replacement. I lost half the stickers from the Welz versions.
