^^^ Rustproofing ^^^

Anyone that says these don't rust has never taken the sill covers off, arch liners off or checked the car properly underneath. They can pass
M.O.T's because they can't see where the rust is and usually holes are but they really shouldn't be passing them at all from what I've seen.


My advice is to take off the sill covers, and arch liners and also if you as re like me the rear bumper because you can see inside the rear chassis legs from there.
These are the first things I do when I buy one. I have owned 5 of them and they are all the same!
If people want these cars to be here in the future then they need to be sorted just now before it's too late.

I must have been lucky with some of that rust traps. Both my delta brackets were shot and the n/s/r bumper bracket rusted away. But under the rear arches were ok for me, phew

The thing that made my heart sink was all the studs that hold up the exhaust heat shield and the some of the plastic fuel lines. Its the same studs that are used to hold on the plastic wheel arch protectors too. I was lucky in the wheel arches but some of the studs are half the size they once were.
My advice would be to remove the plastic nuts on them and give the stud a good blob of grease while you still can




The only thing I could find that fit the bill to replace the stud things was to modify some roofing bolts and weld them into the patches

These cars can also develop rot on the rear frame rails where the boot floor is attached, not at all hard to fix, very easy to cut out and weld in new material though never seen one actuality go through, normally just a clean and underseal before its 20th birthday will suffice.

I found a little under the battery tray on mine, nothing major, just sanded it off and put several coats of red oxide paint.

Default Wheel-arch rust?

I've seen enough to think they don't rust in the wheel-arch, not a brack on any of mine, not even close, yet flicking thru' eBay I see this. It's a piccy of a Darwen based car. The UK corrosion map has it as a more corrosion prone area compared to most. Maybe this here is proof-positive, there's something in one area over another?

The front wings perforated on mine where the wings meet the front bumper. The paint was externally perfect, these had rusted from behind and the rot had run rampant out of sight so by the time it bubbled on the surface I could see they were already mullered.

DANGER- Your Sunroof

I understand near all Yank-side cars have sunroofs, more of an option our side of the pond. It's not unheard of for sunroofs to simply lift-off and clomp following traffic. A sheet-metal stamped-frame is bonded to the glass. Water sits in the seal and rots the stamping. Eventually there's nothing to hold the glass to the stamped-frame, and wompf, the wind lifts it off. The vehicle behind sees your sun-roof assembly. Not good.

Check yours.
It isn't because testers don't know about it. Should be an MOT fail. Pound to a penny, yours won't be good. Mine was found in a very bad way. A firm push would have seen it go to lift-off.
