!  Note: Due to a change by Firemonkeys in Version 8.4 that reduced the PR of the CHEVROLET CAMARO SS (2017), the upgrade path for 100% completion has changed. Firemonkeys have acknowledged that they will lower the Required Maximum PR to complete Maximum Muscle in the next update to bring it in line with the prior upgrade path. It is advised that you wait for this change in order to optimize your upgrade costs for series completion.  ! 

See three of the most formidable car manufacturers face-off in this muscle car showdown!
