This is an odd one to bring back.
The AHM C-LINER can be made into a decent looking model with some work. The oldest ones with the 5-pole motors also ran pretty decent. They got pretty hit and miss later on though, as they kept getting cheaper and cheaper until they were essentially a toy you'd find at department stores.
