Some more pointers:
Check online, like on eBay, for available key fobs. If the listed car only has one and you lose it, you’re out of luck. It’s also possible to leave the fob inside the car by accident, and then the car locks (sometimes on its own) and you have to break in to get it. You can only use Kizashi fobs (no aftermarket stuff or identical looking Nissan fobs) as far as I know. There’s a specific term that’s used to describe the type of fob you want, and while I forget what it’s called it lets you link it to your Kizashi. The type you don’t want won’t let you link it unless a locksmith unlocks it or something. On that note, make sure there’s someone in your area who can work on car key fobs like the Kizashi’s.
2013 Kizashis didn’t come standard with spare tires, but rather a tire patch kit and compressor, in order to save weight for the sake of fuel economy. It’s possible to get a spare from a Kizashi through a place like eBay, which is what I did for my 2013 Kizashi. If you go to the seller to inspect the car I’d suggest checking under the trunk floor, just to be sure.
If you test drive the Kizashi, be sure to take it to a nearby independent mechanic to look the car over. They can tell you if the car has been in an accident or has quirks that the dealer might not disclose. Call a well-regarded mechanic ahead of the test drive; they should be able to do it for free. If the dealer won’t let you do it, I’d pass on the car because that suggests they might be hiding something.
Also, ask the seller if they changed anything like the battery, the oil and oil filter, or the tires. I thought mine did all of those, but the oil seemed to be really old and dirty when I changed it a little over a year from getting the car. Like much more so than a year with the same oil lol. The guy at the DIY shop I did this at kept going “wow that should have been changed a long time ago.” Knowing the oil one will help you know when to change the oil for the first time.
Some of this isn’t Kizashi-specific but since it’s your first car purchase I hope it helps with whatever car you choose.
I personally like the look of the Kizashi trims with Sport in the name. Or whatever gets you the sporty look. I lucked out when a GTS Sport became available, but I might have bought a non-Sport model as well. But if I did I would probably be kicking myself because I really like the chrome trim around the foglights, the slightly different grill, and the 18-inch wheels that look great. I’m honestly not a fan of the other wheel designs on the Kizashi.
