What are the pros and cons of a 1990 Mercedes-Benz SEC?

I'm about to yield to the long standing desire to buy a Mercedes-Benz 560 SEC. I have located a 1990 car with less then 100,000 miles and in outstanding condition. What are the pros and cons of buying such a car?
MBUK was one once owned by Nigel Mansell and then Brian Sewell. Drives beautifully, but doesn't brake like a modern car. There is a nest of worms. Take the air filter off and if you see any oil under there the car needs maybe £10,000 of work on the engine. Make sure all the electrics work: ALL of them. Magnet test the body for bondo filler over rust. Definitely have the underside inspected by an expert for rusted brake and fuel lines and leaks.
