Im considerin buying a 99 SE auto with 95k on it. I know for a fact that milage isnt a concern as far as reliabilty goes, but what I was wondering is if I decided to do some mods like intake exhuast any maybe a few other small upgrades would I have to worry about this decreasing the relaibility of the engine becuase of such high miles? Thanks.

 

with the proper maintenance, the maxima has been known to go 200k+. Find out how the car was treated before you buy it. An intake or exhaust won't degrade your reliability, depending on what you're looking to do.
