These things are bad for rust I think mate... was towards the end of the period where Merc had cut costs so the cars weren't needlessly over engineered anymore. I actually got told they werent galvanising the shells at that time, but not sure how likely or true that was.

They go like stink though, remember having a blast with one in an old car of mine and it was surprising what the big Merc was able to do.
