On the contrary, if it is a very early early car, say under VIN 2000, it is highly LIKELY that the rear window was never sealed properly. We see it quite frequently that an early car will seem to have a lot of engine noise in the passenger compartment, and in nearly 100% of the cases, it is a result of a rear window that was never properly installed at the factory. Gently push at the bottom of the rear window from the inside and you can feel it move/hear the noise louder.
