 I purchased this sentra se-r spec v thinking it was going to last forever! boy was i wrong, not only have i put a new tranny, but also a new motor,abs wheel sensor, cruise control ecu, and i am on my third catalitic converter! yea i said three! but now after all that i am afraid to open it up on the highway or eneywhere! I thouth spec v ment sport but mybe not! so now i have to baby it cause if i dont the catalitic converter might overheat and the insides might blow out again! posibly causing the motor to blow,like before, by the way did i metion this spec v is mostly built in MEXICO,just read the original window sticker that should explain everything! so buyers beware and good luck!!!!
