So... I bought a 'mint' and cherished 49000 mile 997.2 C4S from a renowned dealer, and they were great and the car has great provenance. i went into this with my eyes open knowing this was a 10 year old UK car, and asked on various forums about rustproofing. Without exception, every single person told me that Porsche's factory rustproofing would be fine and I wouldn't need to do anything - just use it, rain or shine, winter or summer. I know this wouldn't be the case so the first thing I have done is book it in to a specialist and have all the plastic under trays, sill covers, arch liners and heat shields removed so they can inspect it.
Inevitably they found rust. Everywhere.
Of course, I expected the power coating to have failed after 10 years which of course it had, but I didn't expect the sills to have started to go along the seams.
So, pretty much everything that was concealed is now being cleaned, blasted, treated, painted and then Dinitrol treated, in order to give me peace of mind. I suspect that if I hadn't done this, I would be failing MOTs in a few years.
Pretty much sure everyone will tell me that mine is the exception, but there isn't a single reason to thing it is. Always garaged, used as 2nd car, cherished at main dealer or specialist, etc etc.
As all cars, these are fragile and need proper maintenance - not just the visible bits.
