C257 CLS450 CLS53

The CLS 257 had very big shoes to fill in the USA.  In part because with only large engine performance C218 and C219 made it to the USA previously.  This caused the CLS to have great street credibility and a cult following which introduced many to the brand.  The C257 unfortunately did not bring a V8 model to the USA but did arrive with two strong inline 6 options with the CLS 450 and CLS53 which use a similar engine with a different power adder package and tuning.
