Hmmm, I give you, that most metals can oxydize...but talk to my mechanic, who wanted to buy my truck. Or the tow truck driver who drove my truck on his flatbed to the dealer. He told me, that he has not seen a 1998 F150 in this good condition in a long time. Or my wife's niece, who took over the wife's 1988 Mustang in 2002 and drove it for another 10 years.
It's not hard to explain, just do a yearly rustproofing, here in Canada it's Krown or RustCheck, at $140.00 a crack. After the first 10 years, every second year would probably suffice. Most people wont do it, even though, you can probably make it back when you sell the car, because of its (good) condition.
My neighbour aquired a white Avalanche about 5 years ago. The truck was used, maybe 2 years old when he got it. Looked good. I suggested to go with RustCheck. We are in Ontario, so lots of snow, ice & salt. He said the dealer put one of those electronic gadgets in. I can tell you now, all Avalanches rust, big time. White paint & rust is really ugly.
Guess what I am going to to with the Stinger? Exactly! Because I have the proof in my driveway what works. My father always told me that oil and dirt are the best protection against rust. And I am going to stick with it. Besides, it's cheap insurance.
The only thing that is going to be a PITA are the Stinger's bottom panels. You are probably aware, that the car bottom is almost completely flat for aerodynamic reasons. To get at the brake & fuel lines and the hidden frame parts, these panels probably have to come off for the service. We'll see.
Keep things protected and any car will be fine. For a long time.
