Don't know if my car can be compared to a later model Maxima, but I have a 1979 280ZX with 250,000 miles on it. It has the original fuel pump and starter,(although I have cleaned and relubed the starter bendix a few times in the last 30 years). I replaced the alternator brushes at around 120,000, and the regulator burned up at around 170,000, so I installed a rebuilt alternator that has been working perfectly. The original water pump started leaking at 80,000, and I had to replace the water pump 5 times, as they didn't seem to last very long (new GMB brand, with Autozone lifetime warrantee). No bearing problems, they all had shaft seal leakage issues, and most were infant mortalities. This last water pump has been good to me and now has about 70,000 miles on it. I am kind of embarrased to say that this car still has the original radiator hoses, heater hoses, and fuel hoses on it, but they are inspected frequently. Except for the suspension improvements I have made, and my attempts to lighten the car for better performance/handling, I guess you could say "I don't fix what isn't broke"! This Z has been extremely reliable, and I expect to get well over 300,000 miles out of the original engine and drivetrain, with nothing but normal maintenance.
