Hello everyone,
I just picked up a 2007 G35s Sedan. it has higher mileage at 180K, however it was passed down to me from family. I look forward to getting a few bug fixed and getting the car into a great daily driver condition with a few mods to make more my own... Right off the bat I will be changing all the fluids and spark plugs, is there anything else I should address?
Thanks in advance...

 

I'd focus first on correcting any little deficiencies like broken interior components, give the car a thorough wash / clay / wax to ensure the paint lasts a long time then start working on some of the more obscure fluids that may have never been changed like power steering, brakes, etc.

Power steering is easy, buy 2 bottles of Nissan power steering fluid and a turkey baster, suck all the old fluid out of the reservoir and refill it, do this once a week until you run out of fresh fluid and you've likely sucked most of the contaminated fluid out. Brakes is a bit more of a pita but getting that old fluid out means less chances of premature failure of the components. Same goes for the automatic transmission fluid, drain fill, multiple consecutive weeks if necessary until it doesn't look as dark. With 180k on the clock the vehicle SHOULD HAVE recieved 6 transmission drain/fills but most people like to ignore transmissions until something breaks due to neglect.

What are your long term plans for the vehicle? Something you plan on keeping for a decade or more or is this more of an intermediary vehicle on your way to bigger and better things?
