What does the letter designation mean

From the web....."Automakers use a variety of model designations to denote plain or fancy versions, and there's no rhyme or reason behind the letters and numbers. One company's S model, for example, may be a direct rival for another's SE, LE or LX model. They're just another way of saying Good, Better, Best."

Thanks what do they actually mean so I know what I'm buying

If you are looking at new, go to the Nissan website and look what is available for each designation. The "S" will be the base package.

I purchased a Altima claiming a great deal but only one car he would sell at that price. NO lettering on rear so reading this it is a base mode. Not so fast, car has smart key (can start the car from inside), electric adjustable front seat, chrome interior and exterior, 2 device inputs in rear, rear camera, came with complete floor custom mats, and cruise control . So what is it?

I work as a sales man for Nissan S = Standard SV = Standard Value SR = Sportier Ride SL = Standard Luxury

I just got a 2017 Nissan Sentra SR with 22k on it was kinda afraid of the cvt transmission when should I have the fluids flushed some say 60k some say 80k

What does standard value mean on a Nissan Sentra

In the N15 Nissan Almera the trim levels were LX = either Low Extras or Luxury GX = General Luxury SLX = Super Luxury SR = Sportier Ride GTI = Grand Tourer Injection
