Nissan used to sell the current SE-R and SE-R specV without mention of the word sentra. In fact if you looked through their list of cars, the SE-R would be seperate from the sentra. Then, 2004 they put it back as a sub catagory for sentra. Rightfully so, because it is a sentra. Just like the SRT is a neon. 90% of the car may be different like the SE-R, but the underpinnings are still neon.
