Back in about 2005 a mate bought a Porsche 944 (mid 80's?) that had been owned by one lady from new. Having reached 90 she had given up driving.

Car had never been garaged and possibly never cleaned. Brake dust had become part of the alloys which needed a nuclear blast to clean them.

It had only done 6,000 miles from new and in its later years only used to go the hairdressers once a week.

But it was amazingly rust free despite the fact the the red paint had gone milky over the entire car. He only paid £1500 for the car and accepted it would be a long term project if he actually decided to sort it. As parts it was worth more than he paid.

Does anyone remember an old Top Gear where Chris Goffey recorded an interview with a little old lady who had an AC Cobra?
