Hey everyone, I've been searching around for answers but can't find a decent source anywhere, until I found Nathan's channel and this forum; I'm hoping anyone here could spare some advice!

I found an old 3 series on autotrader that looks really good, here's a link to it:

I wanted to know, roughly how much would maintenance costs on a BMW like this be in 2020+?

Another thing is it seems perhaps too good to be true; for that mileage and price is it likely to be a scam of some sort? Any other 3 series' for about the same mileage cost significantly more, could it just be this one is likely to be in worse condition? Or perhaps I am getting a decent deal I'm not quite sure 😅

If anyone could give me some direction that would mean alot, thank you!
