Hey l was searching on youtube, and to my disapointment, l did not find too many reviews on the infiniti FX 50. Does anyone out their have the FX50? Is the engine noise louder than the fx 35, since it goes 0-60 in 5 sec?

All the newer Infiniti is have tuned exhaust and are not noisy. If you buy one make sure you only service them at the dealer. There are special engine and transmission fluids that any quick lube wo not have. These vehicles are way to technical for the every day mechanic to work on.
l prefer the FX35 over the FX45 or FX50.

it sucks and looks like shit
