I might have missed it, but any mention of why the previous owner got rid of it?

So what I know with my BMW s and other German cars .. battery voltage matters a lot. You have to reset the battery when it is lower vac otherwise it will throw random faults. So reset it now at 80% to see if some of them go away. Also, if you re-coded something that the computer doesn't like it will throw a code. Sometimes it's better just to code everything back to stock including the seatbelt alarms and whatnot and see if the codes will go away permanently. Then change one thing at a time to see if it pops up any codes. I had to learn this with my 2018 BMW X3 after changing a couple things. And one code will definitely generate two or three that belong to the same module if it's not coded correctly. So find all of the original codes and change it back. Just my two cents.
Also all of the codes that start with the same preface are probably generated from the same failure.. I e like the B7F codes and the 803 codes

If it makes you feel any better I also have a bunch of random errors in unsaved section, car runs great though, newer MT as well. Should be fine, send it

I checked the error memory a few days later and all of the codes had went away but one (headunit related.) The info memory still had a ton of events logged, but I've compared this with another supra and it was virtually the same, so at this point my best guess is that I'd treat info memory in bimmerlink as some sort of equivalent to windows event viewer, in the sense that this car logs almost anything and everything regardless of if its an issue or a common log, and bimmerlink will still show it as "errors."
Being that I've tested more than one car and this seems to be the case, I think using the word "errors" under info memory might be a bit alarming to people like me who aren't necessarily familiar with that type of cars architecture.

Mostly logging what happened afterwards in case someone after me has the same problem, but I agree. If there's nothing stored in permanent memory or no CEL, then its likely nothing to worry about.

It's definitely just logging, I think especially if you used Bimmercode to tweak some things, it'll pop some errors if you change the code. But no CEL you should be fine.

$63k for a used GR Supra? I'd go new with that price. I've gotten a few quotes for brand new 2026 Supra's for $4000-5000 off msrp. One was even as low as $58,500 brand new.

Typically I'd be right behind you, but my search to pickup another supra after I regretfully sold my last one has taken me coast to coast. At this point I was tired of traveling and Carmax's 10 day return policy, plus the car being down the street was enough for me to deal with the price. I was beyond jaded at this point from the time and travel.
However, for those that have read this, I did end up returning the car. Not necessarily because it was bad, but the exact same dealer had an exact same spec supra come in that was $1,000 less, had 6,000 less miles on it, two keys as opposed to one, and all four factory tires still on it as opposed to four different tires (same brand on each axle, though) of the one I had just returned.
They let me do an in and out swap. I'd say Carmax was overall a decent experience. The price was higher than if I looked elsewhere, but the convenience and ten day return policy was worth the peace of mind and not having to travel was worth a few grand to me.
Honestly I wouldn't mind doing business with them again, despite some people's concerns.
If I had to guess, when a car comes in they likely do a basic visual inspection and vehicle history check on their cars and not much beyond that.
While I can't speak for anything else outside of my experience, I think the general vibe is that if you want to shop there, plan on having the car looked at by a local dealer or if you have a lift, even better. I don't think they are out to screw people over, but if you don't do your due diligence you are obviously taking on extra risk for no reason. That ten day return policy is pretty generous, they didn't even try to fight me on it.

That's kind of crazy. Any reasonable human would have told you - hmm, keep the car you have, we'll give you a couple grand refund on it. I guess they have an algorithm that decides prices for them and somehow you got lucky (which is awesome, of course).

Yeah the sales guy was like "take the cheaper one with the two keys and fresh tires and low miles and save a grand while doing it." Their algorithm decides all of that, and I guess it just happened to work in my favor on that one. I am not complaining whatsoever.
