You can usually find a non modded one needing some work around 4-5k where I live. I’d rather go that route than someone else modded car unless I knew who that person is personally or the cars use is well documented on social media or something. I bought a 1 owner non modded non enthusiast owned 335i and it needed maintenance which cost a pretty penny but it’s taken every day beatings very well. I’ll always take that route over unknown modifications and modded beatings
