Looks are a personal thing, Navaras Built by Nissan, perfected by owners... Dont think many on this forum have not carried out a modification and personalized their pickups, All to their own
As for suspicion a few photoes of old parts next to new or keeping old parts and offering to new owner on sale ..should put any prospective new owners mind @ rest, Although id imagine if a front end update was done the owner isnt intending on selling soon?
Im just about to strip an immaculate 2009 one owner 20k miles Range Rover Sport Full dealer serviced no expense spared couldn't get a better example ..and facelift it ,Replacing the bumpers`,headlights,grill Just for the hell of it,
The RR`s bumpers vents and grill first time round at less than 500 miles old Still have the originals,
All my toys are modified within a week or so of owning them,
I tend to find it actual adds personality and value not detracts .
