Fair comment. Maybe some people just like the Japanese styling - like myself, and many others I know. It's probably a lot cheaper than your average porsche or ferrari. Besides, it's good to see that the japanese technology can be made to similar calibre to the European cars, which have typically dominated. I think that's worth encouraging.
The GTRs are all limited to 180kmh by Japanese law as well. Not hard to get that removed though.
As we all know, top speed isn't everything. Sure the GTS's can do it, and other cars of course, but the Skyline GTR has heaps else going for it.
Anyway, I was just justifying my statement at the top that a Skyline GTR could do 250. Cos they can!
