Oh, my ! That white one is a pretty wee car. How much do these go for ( & how often do the come up on the market ) ?
Bad news is that they NEVER come up on the market... :-)
There was one green for sale in UK (http://www.race-cars.com/search.cgi?V=02&dx=carsales&ask=g12) but the page is no more viewable, he was asking for £32,750...
It was built in 1999, neither by Ginetta or DARE, but it was road registered as a '70 car and had FIA HTP papers.
At that price you could consider having one newly made from DARE, but you should choose between FIA spec OR road registrable... :-)
There was another one orange on sale in USA on ebay some months ago, this one was built by DARE in the japanese rush period so I guess somewhere in between 1995 and 2005 (?)
The fact is that they are quite rare to find on the market, and for a good reason: why would anyone want to separate himself from such a beauty?
