Thanks. I debated with myself about FSD. I still have the option of deleting it. If I do delete it, I can lower my payments By keeping my down payment the same. or I can keep the Seven grand in reserve, and have the same payments. The former means that I would have to save up to buy FSD later, but in either case FSD would cost me a grand more than I'd be paying if I don't delete it. (Or more if its price increases again.)
All told, most of my driving is freeway (pre COVID19 that is) so NOA is attractive to me.
You will find (likely have already found) that the people on this website who decided not to buy FSD are not shy about telling everyone "its not worth the money" because THEY didnt feel it was worth the money.
Conversely, many (not all, but many) who have it with either say " i think its worth it" or grew tired long ago from having that "discussion" on these boards, so just ignore any "FSD isnt worth it" discussions.
Back to your thread topic, I have a 2018 model 3P, and have been very happy with the car. If you are planning to keep the car for a long time, I would buy new. I dont feel tesla model 3s currently fall into the (generally accepted) principle of "buy the car 1-2 years old and save a bundle!" associated with most used cars in this price range / space. So, I would buy new over used, hard stop, and then delete / decontent to fit the budget if I had to. So I would buy new without FSD over used with, if that was the only way to hit the budget I either needed to, or wanted to hit. I say this as a person who has FSD and happens to think its worth it, by the way.
I just feel "new" is worth MORE than FSD, and luckily on THIS car, its not a "forever" choice like making a choice to decontent some feature or other is on every other vehicle.
If I had to have used for some reason, I personally would be more likely to buy the used car with 28k miles on it, because its likely someone just drove that car a lot. It has a bunch of miles on it, so was likely not much (or any) of a problem. Conversely, I always look "side eyed" at low mileage cars being offered for sale, because my brain always says "why did someeone want out of this car with so little miles on it?".
So, I dont see the value in very low mileage used cars, unless there is a CLEAR explanation for why that is. Clear explanation meaning, for example, Many Corvettes become "garage queen" type cars because they are halo cars for men as they buy a sports car when they can finally afford one later in life, only to find out that "man it hurts getting in and out of that thing when I want to drive it, and man its uncomfortable, and I will just take the SUV to my golf outing this weekend".
So, New over used, or of those cars, if it were me, I would buy the 28k one because it has the most clear reason why its there. The others say to "ME" --- "I was a problem that the owner wanted to get rid of with low miles".
May not be true, but definitely "could" be, and there is no clear reason why its there, unlike the 28k car which was likely some business owner logging highway miles.
