Absoluely agree DM, but they will use the bits from a RHD as well as a LHD. We don't see corrosion on them here either, scrap yards are a great source for good rust free panels, well not that good as most panels here are dented and scraped!!
We used to have one of these when I was a kid, exactly the same in white! It used to be my mums car and I hated the bloody thing. I lost count the amount of times I was late to school because this stupid thing never started in the mornings. That was scrapped and replaced by a Datsun!
Then my dad bought a B-reg W123 230E in red...nice!
