What parts to replace 40k garaged 2003 350z
Hello everyone,
I found a unicorn. A silver 2003 350z in pristine condition with only 40k miles. Hasn't been run in a few years, the owner replaced a few things (exactly what, I don't know yet) and started it up this summer - car started fine. Hasn't been driven in forever but garaged the whole time. I'm looking to buy it - but I know I should replace a bunch of lines and seals. Any advice on what I should replace? Completely new to restoring or fixing cars. I have to use the car in September so I have some time and my friend owns a shop so I can get it done for cheap.
Thank you all in advance for your help! Will post pics if the deal works out 😊

From a guy who bought a 2005 47k mile car.
1. Check the rear bushing where the Diff is mounted, see the black tear of death? Rubber fails and the silicon gel leaks out. Common failure point. New bushing, enjoy, fun project.
2. Check the plugs and see if any oil is leaking into the spark plug area rubber gasket around each plug tends to fail. You will need to replace the valve covers to correct this. If not, you will start to get a mis-fire and or coil failure. Common Issue, particularly on the driver side for some reason. Replace them both if you are in there.
3. Check the shocks for leakage. Two of mine have minor leaks. Just an age thing.
4. The usual, belts and hoses.
Those are the three things they found on my car. I got the first two done. New shocks coming soon. Really, not bad considering you have a 18 year old car. The rubber stuff, just ages..

I would put fresh engine oil and a new filter right off, but even more than that you should look at the mfgr date on your tires and check for dry rot. Personally I wouldn't ride on tires over 5 years old, a spirited ride might end in disaster if the rubber separates from the casing. Gl!

If there are no service records, all fluids should be considered suspect. Consider swapping tranny fluid with Redline MT85, new diff 75W-140 fluid, fresh antifreeze/distilled water, Bleed brakes and put in a good DOT 4 brake fluid. Read the DIY thread on changing all these items and you'll be better informed.

Please let me know about driving to the shop and thank you all so much for the advice. If there are any common issues I can solve while fixing the rest bushing, valve covers, or shocks please please let me know.

If it's running well there's no need to tow it. When to change your oil is always a debate. A general rule is no sooner than 3K miles/no later than 5K for conventional oil. Synthetic is a little longer, mb 5/7.
