Very nice! I like how you incorporated the "cheese grater" grille from the '71. The only suggestion I have is to make it into one of those retina searing colors Plymouth was famous for! Like sassy grass green, plum crazy....just kidding; I know Lego doesn't make those yet.
You are a new star shining in the sky of LEGO cars, before going to your car I just need you to know that I'm so glad to have you in BRICKSonWHEELS! you're so good to our group... About your Muscular beauty; you just did it just the way it should be! just my favorite building style; large scale, accurate shape, studless, and loaded with functions and details, the only thing that you could improve at it is the part right above the front grill(4 studs); needs to be a little bit thin... but this is not a big deal, you could say it's perfect... keep on the great work man >>> peace..
