a 3.23 has 2.3l of engine alot of people believe dat 3.20s r 2.2l 3.23s r 2.5l but they arent..u can call the dealer and check..
if im not mistaking,
from 1999-2001 are the preface models
from 2002 and on are the facelifted models..
i would recommend u a 3.30ci. 330s are faster and stronger then the 3.25s and 3.23s. if urnt on a low budget go for a 330ci Zhp
