>>10102886>so technically out of all variations, those made by Revell are the best diecast models of BMW 850 in 1/18th scaleDepends.
The front and tail lights on the Revell model look really really bad while the ones on the Solido are a lot better and the Otto ones the best with lots of detail. Revell one also lacks detail in many places like around the windows for example (just plain transparent plastic bordering on metal without any black decals or simulated rubber gaskets).
So yeah in terms of looks the others are clearly ahead but if you're after features then the Revell one with all those openings is the best for you I guess.
