Actually,
Nothing is more robust on a LC vs. LX. they are both 200 series, therefore most everything is the same drivetrain wise - usually featuring the same part numbers. Interior items ARE usually different.
The biggest difference I care about is the LC's 18" wheels vs the LX 20" wheels. Again, those would be interchangeable, so mostly a cost/hassle issue. I prefer the 18's.
All the above said. I prefer my '19 LC, but it's not really for any logical reason(s). As much as people tease about the LX, it IS a beast that sips chardonnay

instead of craft beer
