Exhaust in cabin

We still have a little exhaust getting in and I agree our little Addie,Grand daughter can not ride with us until its gone.I found a huge gap at the lower trunk seal, fix it no day light now inside when the trunk is closed:cheers:and the smell is almost gone but there is still a whiff of it.I have look every where now and cant find were its coming,the only thing I can come up with is the door seals I have yet to get new ones,none there now,so could that be an area were its getting in.Hope someone can help us.
