The topic of rust is on the 9-3 II - III on any agenda. The cars are still too young and still too much in everyday life. Neither owners nor Saab workshops are thinking about the future. Still, because the topic comes sooner or later on the table, 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 large inspection in the spring, rust deposits were found on the subsoil. Not relevant for the TÜV and not for immediate action. But topic - and a fundamental decision. Continue driving for a few years to let the rust just rust. Or react?
According to the motto that precaution is always better than welding, the decision was made to rust cure. Of particular interest was the question of what is hidden under the wheel arches? Rust, or best, naked Swedish steel?
Unfortunately, the answer was sobering. Even a modern Saab rusts, just like other cars do. The wheel arches spread a deceptive safety, and after dismantling found on all wheel arches approaches of rust. Also at the reception of the shock absorbers. In all cases so that you could have continued for several years. But in 3, or 4 years, it might have come to a first Durchrostung. On all fenders and on the recordings of the shock absorbers. Why is that? The paint is thin, the wheel arches rub against the bodywork. Dirt and moisture penetrate - and do their work. Certainly slow, but continuous.
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.
