the one car that didn't rust so bad, and lasted very well was the humble Austin Allegro
But who in their right mind would want one? Having said that, I do think the estate shape was an interesting oddity.
The debacle of the Allegro replacing the 1100/1300 (ugly as sin, no perceptible improvement) was an automotive blunder unmatched until Ford introduced the last Escort (ditto). Hell, they're still on the road., but...
As for the Simca 1100, I didn't own one for long enough for it to do anything other than break down. However, my ex-wife's family tell an apocryphal story of a family member's hands disappearing into a large rust hole when the front shock-absorber test was administered to a prospective Simca 1100 purchase.
Do you get the "Gazoline" magazine in France? Pure restoration magic and old cars used rather than garaged, without that peculiar British characteristic of opening a wallet and letting someone else do the job on your "classic" in the faint hope of capital appreciation.
Back on two wheels and pedal power for the moment.
