Another week, another Porsche 930 Slantnose for sale. Seems like they are everywhere, doesn’t it? As soon as the last Slantnose Cabriolet we featured went live, it sold within one day. If red was a bit too outlandish on that particular car, perhaps this 1989 930 Slantnose Cabriolet for sale from our reader Frank may be more to your liking. Painted in a more reserved Black over Linen combination, this car represents the final year for the 930 Turbo, the sole year to feature a 5-speed manual gearbox with the 3.3 liter turbocharged flat-6.
