The point is - anyone who hasn't actually looked at what's going on under their undertray needs to check it out sharpish ...
It's all down to how or were the cars been driven. They take a beating from saturated motorways, especially if their salted.
l've always kept the use of mine to dry days, apart from when you hit that sudden summer down poor on the motorway. The ones where you drive into them, then back to dryness again.
I havn't owned mine from new, but looking at the car underneath when i bought it suggest similar use, as it all looks like new.
I had it up in the air on the ramps last wednesday, as a pre look for the MOT booked for monday with an oil change, & it's still mint.

I'm relatively new to Alfa ownership and have no hidden agenda about bashing Alfa's completely the opposite really as I wished I'd bought one years ago, but I cant buy into the opinion that the subframe rust is down to saturated motorways and salt on the roads. Of course salt does cause corrosion, but thats no different for any other car - Ive got a 1982 Golf GTI and its rust free! Ive accepted its just one of joys of owning a 159 and have had mine waxoyled and will do every year, but we really shouldn't have to unless you live by the sea where salt corrosion is a year round problem
