First post ever! I've had both the m45 and g37 and the one thing I love about infiniti is even with options, the price was lower than base competitor prices. The interiors have also been excellent. My 2006 m45 had a nice nav, keyless entry, lane departure warning, active cruise control, etc for the price of some leather options with BMW. I think the q50 looks good but engine is basically the same as the g37...
I'm on this forum now since I want a m3 or m4 and do European delivery.
