Very few original XKSS Jaguars ever come up for sale and when they do they are priced accordingly and the wonderful copies that were produced by Lynx also command high prices and are rarely available .
The only other replica/continuation/copy or whatever they are called that I personally would consider purchasing is one of the cars produced by Tempero from New Zealand who produce handsome re-creations.
Although its expensive at 265 K$ . It is the one to purchase if you want to own a replica at the very top end of the market.
