2003 Nissan Sentra SE-R Spec V SE-R Spec V 4dr Sedan (2.5L 4cyl 6M)
Not for the Average Joe.
 If you are one of those non car savvy folks with little to no mechanical skills, this is NOT the car for you. Well, unless you have loads of cash at your disposal for repairs. I have owned my SPEC V since 2004, and trust me, changing the oil and basic maintenance just does not cut it for these things. The 2 main issues on this particular model are the butterfly screws inside the intake manifold that NEED to be loctited and the stock exhaust manifold that NEEDS to be replaced with an aftermarket header ASAP after purchase, due to the poor factory design that can cause SERIOUS DAMAGE to your engine. If you enjoy modding, working on cars and learning about them, this car can be very rewarding.
