Classic

Not really the B13 Sentra aka classic is the 91-94 era

I think he means in terms of classifying the car as a "classic car" in order to get the special designation from the state or something...considering that fact, if you have a 1982 Sentra it will qualify as a "classic car" because most states and territories in the USA, if not all, describe "classic cars" as cars that are 20 years or older from their fabrication date (the one that appears in the doorsill sticker), and any car that falls into said category gets a special designation in its registration and titles, gets a special classic car plate and in some cases the state limits its time on the road (e.g: allowing the car owner to drive the car only on weekends) in order to preserve the car's condition.... Now, validating Jimmi's point; the B13 Sentra (1991-1994) has a trim level, or sub-model if you want to call it that way, known as "Classic", besides the others (E, XE, GXE, SE, Limited and SE-R), and the Classic is pretty much a rebadged Sentra E....
