thanks for the comments gys.
chris, i figured that the wheels have lifted the car a bit despite being lowered and if the sills were body coloured it would visually lower it. do you think it looks unfinished without them?
as for the bumpers, yeah they need work. the mrs drove into the back of it and bent the rear one. the front i'm not sure what the problem is but i'm going to have a bash at realigning it.
need to sort the panel gap on the front wings too.
