I got my R in May, had a 2013 for 7 years, put nearly 100k miles on it. It was a great daily driver and true truck, throw shit in the bed, don't worry about it, pretty fast and I set it up pretty well so it was quite capable.
The R is an incredible machine, goes fast, feels fast and is a beast to drive. Responsive as what I expect a GT500 would be in Sport or Baja mode, sounds incredible and looks equally as good.
Is it capable? Sure.... But do I want to jump it, (well I want to), but do I want to load gravel in a $150k cream puff, not sure about that yet. Maybe ask me after 10k miles. It is fun to drive it and it makes you smile every time you fire it up. I know everyone has them, but for me I don't understand the allure of a V6 truck, and never will.
