is this hi poly model to me smoothed out for rendering or low poly model for games?

Red: you have way too much edge loops, add this much density of edge loops only when you need sharp edges of model, or extra detail, not just that you waste polygons, but you add sharpness on parts that you want round, that will make them bumpy because it is hard to handle such poly density to make nice round shapes
Green: you lack some edge loops to add more roundness to model (very important in low poly), also try to make polygons as square as possible avoiding diamond polys as much as possible, you have some extremely stretched rectangles in model, that are not acceptable by any means. long rectangles are acceptable in support edges for hi poly, or specific details, not in the middle of flat part of door
Orange: really avoid adding vertex with three or five edges coming out of it on critical corners of model, for example you have rally important sharp corner over the wheel, and that multi edge vertex will do no good to shape
For low poly games, triangles are acceptable check this, the flat surfaces have a bit less poly density and round surfaces have higher poly density 4edged vertex used on sharp corners of model 
For hi poly

check how regular poligon sizes are, how edge loops flow and how are polygons mostly quads.
Also dont be scared to go for higher poly if you need, my ferrari has over 5 million poly and i havent even started to work on interior
