I assume you are talking about exhaust fumes in which case I recently had this problem with my '85 wagon except that I could only smell the fumes when I had the sunroof open. The problem was a hole in the top of the forward muffler that was allowing fumes to accumulate under the car, even at fairly high speeds. When I opened the sunroof it created a vacuum that drew the fumes into the passenger compartment around the rear of the car. When I replaced the exhaust the problem completely went away. I discovered the leak by crawling under the car with the engine running and feeling all around the exhaust until I could feel the leak. You may want to do this with a cold engine/exhaust and obviously block the wheels really well.
