I suppose one of the great things about cars is there is always more to learn. Today’s car is one of those moments where I was pleasantly surprised to learn something totally new. You might be looking at that photo above and saying “Yes, that is a 1997 911 Turbo S.” I also as a reasonable person with Porsche knowledge jumping to that conclusion also. Why? All the 993 Turbo S cars have unique venting in the rear quarter panels I thought were only used on that model. Not even the standard 993 Turbo has it. Well, the car we are looking at today is a 1997 911 Carrera S. How did it get those vents in the front of the rear wheel arches? Apparently, it was a very rare option. If you ordered “X79 – Side air vents on rear wings” you could have those little vents, but considering this is the first non-Turbo S I’ve ever seen them on, I’d say they are pretty rare.
