A Nissan Fairlady Z Z32 (aka 300ZX) - one of nicest Japanese sports cars in my opinion - convertible is not big news, however one with a folding hardtop is! The production cabriolet version went on sale in 1993, along with the T-top and standard versions, but before this, in 1991 Nissan produced a concept version that was shown at a number of auto shows. The concept featured a power-folding, retractable hardtop.
The concept was built with American Sunroof Corporation (ASC) and it is now for sale on eBay, with a Buy-It-Now price of $62,000. Power is provided by the standard 3.0L V6, mated to a five-speed manual gearbox. The car has only 8,202 miles on the clock. According to the seller's listing, the original build cost was in excess of $800,000.
And just some history... Nissan utilized the Cray-II supercomputer to completely design the 300ZX with a form of CAD software. This made the 300ZX one of the first production cars to be developed in a CAD program!
