Hey up lads, another update from today's fiddling and stuff.
I had all the trim out of the boot, and had a good hoover out, including rust, which revealed that once again, the arch was begining to go, and, more worryingly, there is a *small hole near the fuel filler. I also noticed that the clattering sound I'd noticed is actually coming from the end of the exhaust, as the tail pipe is up against the chassis.

All five tyres are Dunlop SP44J 195 SR15's
So far, all the bad stuff seems to be on the drivers side, whilst the passenger side is much more clean and tidy.

Also, being a 410, it doesn't have an anti-roll bar. As I'm not planning much in the way of off-road, does anyone have one they have taken off that they would otherwise scrap? I'm in North Lincolnshire, between Scunthorpe and Grimsby.
