i have an e36 316i sedan , and i'm to trade it in a coupe ( 316i also ) coz we have very high customs on cars above 1600 cc , so i waz asking what's the difference between its chasis and any e36 chasis and the m3 too , coz i was thinking to upgrade it to a m3 with all its kit (engine,interior,suspention,etc...) , is this possible or i'm just dreaming.
