There are many variations of the Z based (on era/decade) and they have all made impact in their own way. The First time I saw a 300zx on the road was spectacular, such presence and character. However, the 240 and 260 made the most impact. Undeniably, the most beautiful and not just amongst other Zs but other cars.
Similarly, the 1970 Porsche 911 was one of the best design and most revered. Singer successfully created a masterpiece (watch below) and leaves a legacy despite the modern evolution of Porsche.
I'm a late discoverer of the 70s Z, but in my books the best looking/driving/priced car. The e-type linden knocker low drag coupe (recreation available) and Porsche singer are both art on wheels and commanding price tags of above $200k. We are talking about Porsche's and Jags (look below) here!
In equal stead, the Z needs the same (a recreation) treatment, but priced accordingly. Having lived in UK for 7 years I know it's possible there because of investment appetite, engineering expertise, low labour cost and automotive passion. The question is who and when? I hope soon......
