I've never owned one, but I seem to recall they were all galvanised, so pretty rust resistant by the standards of the time.
Not cheap to run and you'll need a specialist - I don't imagine they feel quite as quick as they did when I test drove one, when they were current, I decided I'd not keep my license long if I'd actually bought it!
The salesman and my wife both had it up to 120 on the test drive! Different times...
