I think choosing yellow as the background color is the best choice when it comes to Bat vehicles. I based the background color on the bat symbol for most Batman versions that has the same color on its background. The background blends well with the Batmobile pretty much like a bat symbol in vehicle form. The model looks really cool because it is very similar to the actual Batmobile in the movie despite its size. The gaps are present on the parts like the flaps and front wheels. I believe this Tomica version is one of the best when it comes to the 1:64 scale. This Batmobile 4th can be a challenge to find today in the secondary market. if you plan to get this one in your collection.
