The Vs have 19" wheels,wider tires (larger on the rear),bigger drilled brake rotors,larger brake calipers,larger rear differential,larger rear axles,external engine oil cooler and transmission cooler,they both have the 6 speed automatic (as of '07),of course the 4.4L S/C engine,both cars use the V hood(starting in '09),different wood and metal trim in interior,suede inserts in the seats and on the doors,no wood on the steering wheel on the V,larger exhaust (2.5") with bi-mode mufflers,mesh upper and lower grills,different exhaust tips on the Platinum edition,factory installed rear sway bar on the V and no adaptive cruise control on the V. I hope this helps.
