Yeah you'll be fine. I don't have any experience with Nissans, but all cars have their own annoying quirks, even if some are more annoying than others. Just start small: find the Fumoto valve for your car, do your own oil change next time, and install the Fumoto valve while you have the oil drained. A good starting point is the maintenance schedule in your owner's manual, though sometimes Haynes has their own ideas, and some Internet research can help a lot. Do your own cabin air filter, engine air filter, oil filter, tire changes if you live in an area that gets winter (you will have to buy a second set of rims if you don't have them already, tire crackers are way too expensive for weekend warriors and don't even think about cracking a tire without a machine), and you will already be saving hundreds a year in maintenance, and none of those require special tools unless you want to go for an impact wrench for your lug nuts--to take them off only! You should always put them back on with a torque wrench or at least by hand with a socket wrench. Blasting lugs back on with an air wrench is the best way to get seized lug nuts next season.
Once you have some experience doing the easy stuff, move onto brake pads, brake rotors, brake line flushes, coolant drain & fill, transmission drain & fill/filter, fuel filter, power steering fluid, etc. and you are doing 99% of your typical maintenance on most cars. It ain't glamorous, but it's a great way to save a lot of money (all shops are ripoffs, yes, even the good ones) and the ladies love a man who can do stuff themselves like fixing their cars
Get a print manual if you can find one for a reasonable price. You will thank me when you're on a crawler under your car, covered in grease up to your elbows, wondering "where the fuck is that bolt again?" and you can just look over at the manual you held open with a hammer on one side and your 10 mm on the other. Phone stays on the tool caddy at all times, as I have learnt the hard way.
