The topic of rust is not on the agenda of the 9-3 II - III. The cars are still too young and still on the road too much in everyday life. Neither owners nor Saab workshops worry about the future. Still, because the topic comes up sooner or later, at the latest when you feel the desire to continue driving a Saab.
Our 9-3 III was first approved for road traffic just prior to 7 years ago. And because at Saab, during the short Spyker era, the 9-3 was given no additional protection at the Saab Zentrum Bamberg. Since then, he has been moved throughout the year in everyday life, without any limit. The winter and the salt have left their mark.
During a major inspection in the spring, rust deposits were found on the underbody. Not relevant for the TÜV and not for immediate action. But topic - and a fundamental decision. Keep going for a few years, just let the grate be rust. Or react?
According to the motto that prevention is always better than welding, the decision to cure rust was made. Of particular interest was the question of what is hidden under the wheel arch liners? Rust, or the best, bright Swedish steel?
Unfortunately, the answer was sobering. Even a modern Saab rusts like other cars do. The wheel arch liners provide deceptive safety, and after dismantling, there were signs of rust on all wheel arches. Likewise on the shock absorber mount. In all cases in such a way that one could have continued for several years. But in 3 or 4 years there might have been a first rusting. On all fenders and on the mounts of the shock absorbers. Why is that? The paint is thin, the wheel arch liners rub against the body. Dirt and moisture penetrate - and do their job. Certainly slowly, but continuously.
Rust: Provision is cheaper than welding.
Is the Saab 9-3 a roster? Is not he. With average care would have noticed nothing without the dismantling of the wheel wells. The Saab could possibly be moved 10 or 15 years without anything happening. But sooner or later there would have been a major refurbishment or disposal due to total economic damage.
In Bamberg the underbody of the 9-3 was sanded off, applied primer with rust and corrosion protection and everything was resealed. A time-consuming operation that took several days. In the end, the rust protection was better than ex works, the body prepared for several more years. Together with the other work, wishbones with side rails, heated seats and air conditioning was finally an 4-digit amount on the bill. Is this expensive?
Is not it. If one compares the effort for a really good, profound rust prevention with the possible costs for a reorganization with Durchrostung, then precaution is in any case more favorable than welding. Prophylaxis is advised. It does not matter if it's just a station wagon or maybe a rare Turbo X or Cabriolet.
