Teslas all come with a J1772 charging adapter, so you should be able to use anybody's level 2 charger. Pretty sure they are all J1772.
Be sure that the used car comes with the adapter. If not, you'll need to buy one from Tesla (or a third party). I expect most Tesla stores have them in stock. All current non-Tesla EVs sold for the North American market have J1772 plugs. These are used for slow charging, so they're useful on road trips mainly for overnight charging.
There are also
CCS adapters, which enable newer Teslas to DC fast charge (similar to Supercharging) at third-party DC fast chargers like those operated by Electrify America, EVgo, and ChargePoint. This could be very helpful if you're looking at a cross-country road trip to pick up a used Tesla. There's one huge caveat, though: A 2018-2019 Tesla will most likely lack the chip needed to "speak" the CCS protocol, thus rendering most of these adapters useless. IIRC, the CCS-enabled chip was added to the Model 3 in late 2020. Tesla says they'll be offering a retrofit early in 2023. It's possible to do this with an
unofficial hack today, but IMHO it's better to wait for the official update from Tesla, even if it means using Superchargers and foregoing third-party CCS charging on a road trip. (Superchargers are better, overall; but it's nice to have the option to use CCS as a backup and to expand the range of possible charging stops.)
I know some will disagree with me, but FSD is worth absolutely zero. It's beta software, and people are paying Tesla $15k to sign up as beta testers.
I mostly agree. The current state of the FSD-on-city-streets feature is that it's harder to use than driving normally, IMHO. It's likely to improve in the future, but I'm skeptical that it will ever be worth the $9,000 it costs (on top of the $6,000 that Advanced Autopilot costs, which is a bit on the high side for its functionality, IMHO, but at least AAP is mostly functional today).
A few people on here have said they donāt use fsd and itās not worth it. I only used it in my test drive and I thought it was perty damn cool. Then again it was my first time in a Tesla and felt like I was in a spaceship lol.
Cool? Yes. Impressive? Yes. Useful? No. It's erratic enough that it does
NOT help with driving. I say that "FSD" doesn't really mean "full self driving"; it means "flaky student driver," because that's the way the car drives. (In fact, that might be an insult to student drivers.) When using FSD, you have to be very alert to the car doing absolutely brain-dead stupid things, like wobbling between two lanes or stopping at a red light only to start moving forward while the light is still red. When I drive myself, it's rare for another motorist to honk at me; but when I use FSD, it happens quite frequently, because FSD does such stupid things. Musk keeps promising huge improvements with the next release, but when the next release comes, it's always provided modest improvements at best. At the rate of improvement we've seen over the past year or so, I might be willing to trust the system to be more than a novelty gimmick in 5-10 years. If it's near the end of that range, then I expect my Tesla will be close to ready for the scrap heap. (Fortunately, I paid just $5,000 for FSD, when Advanced Autopilot wasn't available as a separate option, so I consider that $5,000 spent for Advanced Autopilot, and that makes the purchase as a whole OK -- although even $5,000 for Advanced Autopilot is a little high, IMHO.)
If you're buying a used car that already includes the FSD package, then you can certainly activate it; but I wouldn't recommend paying much extra for this feature.
Nevada charged me no tax. I only paid NE sales tax and dmv fees, as if I had bought locally.
I don't know about Nevada and Nebraska specifically, but some states have reciprocal arrangements in which a resident of one state can buy a car in the other and pay sales tax in the resident's state, not in the seller's state. That's true of Rhode Island (where I live) and Massachusetts, for instance. That said, I've heard of such arrangements mostly in neighboring states, which doesn't describe Nevada and Nebraska, so it could well be that Nevada has such policies for all out-of-state residents. This issue varies so much from one state to another, though, that I'd recommend calling the seller (if it's a car dealership or Tesla store) to get the details. Following up with the DMV or a sales tax office in the selling state might be in order, too, in case the dealer, ahem, miscommunicates something.
What a fun car ! Haha never would I ever think Iād want one, but now I want one!
