I was looking under a 3 year old, 36,000 mile Skoda Fabia a few weeks ago (belongs to the wife of a member on here) and was amazed at the depth of stone chip & seam seal, and the thickness of steel used for suspension arms - very impressive.
The only surface rust I could see was slight and on a small body brace, across the exhaust tunnel.
Thinking back to how Skoda and Jaguar were placed, say 40 years ago (....who remembers the Estelle....
), I know which one I'd be buying tomorrow
