This snapshot is from a 2013 335i and it seems kind of sus.
Does it seem likely that they neglected doing oil changes for this entire period they had it (just over a year and 25k miles) and then just dumped it at an auction because they knew they fucked the engine?
Are there any obvious signs I could look for if I were to go check out the car in person? It would be cool if they kept receipts of them purchasing oil and oil filters, but I doubt that's the case.
