Hello.
Long time since I've posted, but exobex sent the thread to me, so thought I'd add my views.
I currently have an R32 Skyline Gtr and they are extremely rapid. Mine has been modified, but even in standard trim they go very well.
The handling takes a while to get used to, as they tend to corner better than you'd expect. They are very thirsty animals tho! and I regularly see single figures in my fuel economy if driven hard. But you will see low 20's if driven sensibly.
I've owned a few Supra's and they are a different beast to the Skyline, personally I prefer the look of the Supra, but that's just my opinion. What I like about the Skyline, is the driving experience, it just feels more composed. (again my opinion)and the fact that you don't see many of them about, as compared to the Supra. (around my neck of the woods anyway!)
You are quite right about the prices (unfortunately for me!) thay are dropping quite a bit these days, but as always, beware of thrashed examples.
Hope this helps? and if you need any more info, let me or exobex know.
Regards,
Ade.
