Not AREX Cefiro , a "Nissan" cefiro
"Arex" is a model made by Yulon from 1993-95

And (quote from wiki)
"Until the introduction of the Nissan branded Cefiro A32 (in February 1996), the various license-built Nissans had all been branded Yue Loong (Yulon after 1992)"

In short , a 1998 Cefiro A33 would never sold under the brand name of "Yulon" (The usage of Yulon brand on cars discontinued in '95 , after the discontinue of Arex [601] model),
or "AREX" (it's only a short lived model , not a brand.)
