Every convertible that's more than 40 years old exhibits wind noise at highway speeds, even with new weather strips or rubber seals. It's just the way it is with convertibles, an integral part of driving one. Our Pagodas were well engineered for their time, above of other car brands, but wind noise is noticeable on mine above 40 Mph, let alone 120 kph (75 mph) with the soft top up. With the hard top in place, wind roar is less noticeable but still present.
