BUYING GUIDE Mk3 Golf Rust

[Wayne]

They're riveted from the factory so if yours had screws holding it on then it's been taken off at some point in it's life and not re-fitted correctly. This would explain why yours became so rusty due to the ingress of water through all the poxy screw holes.

We are talking about sill trim yes? I didn't think sill trim was riveted on?

They are not, screws are fitted from new I even checked with VW

You are correct, screws along the bottom and a pop rivet at either end. But if you undo the screws at the bottom edge then you can peal it up for a sneaky peak.

As regards to arches, you can try to peal them back for a look but the best bet is to see if you can move the arch at all due to the rivets on them being rotted out. ( Ive seen this alot).

Sorry yes of course the lower section of the sills are screwed on, for some reason i started thinking about arch trims. Doh!

So later mk3 = cheap steel and rust
Early mk3 = not galvanised and rust

Im not going tohave to get a mk4 am I lol.

Early MK3 is like a mk2, absolutly sh!t loads of underseal and rust protection covering all the underbody, inside the doors, basically all the places where you dont see

late cars dont have any of this but have a crappy galvernised ssteel thats not much cop

Ben had a car thats worse than the one in the pic,  the 1997 highline we broke for his engine, he still has it on his drive.
