I've always associated them with 1960s and '70s TV and movie villains, but this Jaguar S-type on eBay is owned (and being sold by) Burlesque superstar Dita Von Teese. if you want confirmation of that, she has confirmed it on her Twitter feed.
It's a rather tasty 1965 model with 70,000 on the clock, one that looks to have had a lot of care and attention thrown at it – new paint job, new front and rear rubber seals, new new brake system etc etc. There's also a black leather interior, wool carpets and 'roses etched in the glass'.
It 'runs and drives very nice' apparently and comes with a personal note to the buyer along with a signed photo. Note that it's a left-hand drive and located in California. Bidding right now is at $5,100.05 with no reserve. Lots more images on the listing page.
