Rust. Where exactly did that go? It usually lived in the sills and made your used purchase terminal in the old days. For the past 20-odd years, though, rot has been fairly low down on the ‘what to look for’ list. Mostly, it seems to be cosmetic.
Rust, then, is confined to all the rubbish from the 1960s, 1970s and early 1980s that would disintegrate before your very eyes after a couple of salty winters. Except that rust never actually went away. I have come across a few Mercedes-Benz CLKs and the odd E-Class from the famously fragile W210 era that have looked awfully crumbly. Late 1990s Fords weren’t great, either. Fiestas and, in particular, Kas and Pumas would crumble quite alarmingly.
That was then, but right now I am indebted to reader Nick Williams, who recently bought a 2008 Honda Accord 2.4 automatic. He described it as fantastic “with every extra imaginable, but it had a rusting sunroof at the front. I think prospective buyers and current owners should peel back the rubberand look for any rust.”
