2006 Nissan Sentra SE-R Spec V SE-R Spec V 4dr Sedan (2.5L 4cyl 6M)
Six months since purchase of Spec V...
 I have had my Spec V for 6 months.  The only time I have had it in the garage was for Oil changes which I gladly perform myself.  It is very reliable, I even learned to drive stick with this car and it does not seem to give.  My only Mod is a NISMO Cold-Air Intake.  It was definatly worth $230.  The CAI does also improve gas mileage about 5-10%. The engine is so much louder after I put it on and pushed the gas to the floor. It certainly has more punch. I plan on getting at least exhaust headers and a Cat-back system.
