It's still possible for me to buy Q50 RS 400 in the future. If US economy is not so good in the future, I will buy used Q50S instead of GT-R and give GSF to my wife. But I will still put good European coilover on it. So for work commute I drive Q50S. For family I drive GSF. It sounds like very good plan, right?
If you think it's too expensive... Sure no problem. You can buy used one like me.(Actually I like used cars more because I don't need to worry about scratch here and there) Less than 3 years normal use for them is nothing. They are very reliable even though the condition is so so.
I also believe that Q50S with good coilover + stiffer sway bars will have more fun than my current stock GSF. I cannot wait for my Q50S with new turbo engine...
I think Nissan Taiwan will import 3.0t engine in the future. It's just a matter of time. I'm also waiting. Don't be hurt. It will be well worth the wait... (You know. Japanese is always very slow...)
