Have Monaros become very rusty ?

I had a CV8 a few years ago and there were reports of them going a bit rusty after only a handful of years.
Just wondered what they are like now ?
Is it a concern now ? Any wheel arches starting to rot ?
They are not what I would call rusty cars, I'm on my second and neither were or are rotten. The actual shell on mine is totally rust free, although I can't see what's behind the skirts. Will be having some paint soon, so will report those findings later.Just wondered what they are like now ?

My chassis is holding up well, but some cars are rotting on the front legs where moisture gets between the skins of metal.
A lot will depend on the type of usage too. Many of these are a second car/toy/hobby. Mine for example has been SORN and garaged since 1st of November and won't be seeing the road till April. Compare that to someone who uses their Monaro as a daily in all weathers, there might be quite a difference underneath.
Many have also had extra weather proofing applied now, I did both of mine.
I wouldn't be any more concerned than with any other ~14/15 year old car, but as always I'd check best I could.
Have a read of this thread - mega mile Monaro doing very well. Updated just yesterday.
This Ro has 235k on the clock and its owner of over 6 years is very happy with it....

I think the rust issue on a half decent Monaro shouldn't be too bad.
They all seem to suffer from rusty fuel and brake pipes, and as previously mentioned check the front chassis rails for rot, problems in that area would be a real ball acher.
The visible body work on the cars I've seen have all been OK, so the only other area I can think of would be behind the side skirts, especially the area in front of the rear wheels behind the plastic end caps. I've emptied out plenty of rubbish built up in there.

My 54k 2004 CV8 has developed a blister on the offside chassis leg under the abs unit.
Closer inspection/prodding lead to 2 small penny size holes! Access to this area to repair is poor so engine is currently out to repair properly.
Rear brake lines and PAS pipes are rather crusty too so I'm taking the opportunity to replace these while the engine is out.
On the whole the car is very tidy, but one small scab has lead to an engine out job!

That's why mines never seeing a salty or wintery road again! Mine has a small blister on the underside of the OS chassis leg. Just behind the steering rack.

Ok thanks guys. Definitely something to look out for then.
It's odd, when the problems first started to appear a guy from Vauxhall came on here saying they had the same protection as other Vauxhall's.
The Vanxhall Monaro/ Pontiac GTO / Holden Monaro all had the same basic rust protection in that they had a 6 year /100,000 mile rust through warranty. ( Chassis and body panels )It's odd, when the problems first started to appear a guy from Vauxhall came on here saying they had the same protection as other Vauxhall's.
The Pontiac version was supposed to sell in big numbers in the USA and they needed corrosion protection because the Americans use salt on their roads. (Presumably the Australian versions didn't have any protection prior to that?)
This is where the additional rust protection came from, If it wasn't for the GTO we probably wouldn't have a Vauxhall version. They certainly wouldn't last very long in our lovely damp salt ridden climate without it.
As long as the car didn't rust out within the warranty period GM were happy.
Having said that Monaro body work seems to last quite well, so overall things aren't too bad.
Thankfully it's pretty easy to keep the rot at bay, a pain in the arse manybe but easy nonetheless.
My car doesn't see much in the way of salt or mud, but I still keep the underside clean and top up the corrosion protection with whatever I have lying around the garage. So far it's seems to be working.
