[Tigers] Exhaust smell

[CoolVT at aol.com]

Had my top up for the first time in about 3 years the  other day.  With the 
top up I've always had an exhaust smell in the  car.  I haven't had the 
hard top on for about 10 yrs., but I think I had  the same problem with that.
So, what's the consensus of the cause?  There are  no exhaust leaks and the 
tail pipe ends go just about to the edge of the  bumper.  The trunk lid has 
the original rubber which isn't torn, but  probably doesn't seal that well.
I figure the smell has to be coming in under the  trunk lid, around the 
bottom of the soft top or in through the windows that  don't fit all that tight.
Years ago I actually sealed the area pretty well  between the trunk and the 
interior of the cars...removed the floppy piece of  vinyl and put in thin 
plywood covered with carpet. Also used fiberglass  insulation and sealed all 
the cracks.  That didn't seem to help much.   So, at that time my theory was 
the smell must be coming in around the bottom of  the top or around the 
windows.
Do these things build up some kind of negative  pressure inside the 
passenger compartment?
Would sure like to get rid of that  smell.
