As in done with all 3Bs because they're just too much nowadays or that particular one?
Sounds like In general. For sure his, but he regularly posts to people not to spend money on a 3b. Underpowered, old, parts getting scarce and a Terrible fit for todays roads.
Sure there are lots of people that still use them, but in reality they are pretty terrible on the highway, and way worse at elevation or in the mountains. Turbo is the remedy, but you are playing with fire with a 3b and a turbo IMO. Some have had good luck, I’m not all doom and gloom.
If you got a hell of a deal on one, I’d say do it and accept it for what it is if you want a project.
