I have a white carat with gray interior... 

My question is... what if I had black leather door panels up front... and black leather front seats.... (the door vent is black you know... as is the dash... ) and black carpet mats up front... with charcoal carpet.. but still had rear upholstery and sliding door side panel in gray... would this be nice and modern, more seemless.. or garish.. and juxtoposed...???
