Vin: When I built the car,I designed it ,specifically, not to have a top. I had a 911 Porsche Targa for 17 years and for the last 7 years, that I had it, the top was never on. Besides, my V8 Z has a top (hehe). The only annoyance that i've had , has been the wind buffetting from the rear and hitting me in the back of the head. I made a temporary plexi windscreen that fit behind the seats and that has helped tremendously. In fact, I went to the NJ Z club show in the fall . Temps were in the low 40's in the morning, I had a ski sweater and baseball cap on and was not uncomfortable on a 120 mile trip. Of course, people looked at me like I was nuts! AL
