The Indicator body set (2.85m wheelbase shown) may need a greater range for its RearLength (trunk) morphing zone, which I find to be a bit too short at present:
Another minor issue is that the roll angle is a bit on the high side unless the ride height is lowered considerably and/or the suspension is significantly stiffened - a potential hindrance with comfort-focused builds. Most significantly of all, however, this is the largest 90-degree DOHC 4v V8 engine that can fit in right now (other sizes have lower or higher engine width limits):
Given that other similarly sized bodies generally have (much) wider engine bays capable of accommodating even bigger V8s, it would make sense to widen the ones in the Indicator body sets.
By the way, what is the Indicator body set meant to resemble the most, and what real-life car body is the Indicator name a reference to?
