While completely true; you didn't post a pic of a GM small block vehicle there.Between the GM small block and the Chrysler HEMI, the US auto industry owned affordable high performance for decades.
Also what I have read: Chrysler developed the platform in-house & from the start as RWD. Daimler forced some rear suspension hard points off on Chrysler, which required re-engineering, then charged them royalties and engineering fees for something already fully amortized.I have read that LX platform had some Mercedes components but was primarily a Chrysler developed platform and not the prior generation E class platform.
