This car had a legendary ad campaign. It was marketed to yuppies, with a commercial featuring a yuppie wearing a black suit. Despite the big ad campaign, the J30 was a failure.
One of the most disappointing features of the J30 is the lack of interior room. Some have remarked that it's a mid-size luxury car with the interior room of an econobox. People tend to ignore interior room when they are buying roadsters and sports cars, but they expect a little more fro a luxury sedan.
The 3.0L V6 was the only engine produced for this car. It made a respectable 210 horsepower. The engine would also be used in the Nissan 300ZX.
There was a special touring edition of this car, badged the J30t. It included a rear spoiler and a four wheel steering system called HICAS. This was only available in 1993 and 1994.
These cars are available on the used car market, although not particularly common. You can find them listed on eBay.
