Pleased to see there are some Batman fans here and you like those models.
My favourite is also the muscle car
About the large wings on the sportscar, it's probably comes from the "craziness" of the original sketches of an early model the 90's Batmobile (you can see on my website). This feeling was still in my mind when I build it.
I'll have a new model to show soon when the photos have been "Baronized"
