Why are majority of 335s clapped out?

I'm in a decently-sized market, and looking for a 335i.. The seem to be in pretty rough shape, all have 3-4 or more owners and need A LOT of work(Won't pass emissions due to catless downpipe and EGR delete, needing bodywork) What's the deal with this particular car being proned to "hooned" and owned by absolute shitbag owners who do nothing to keep up with maintenance?

FTR, I'm looking for a 1-2 owner 335 with a bible full of maintenance records. I would be lucky to get even oil change receipts from the sellers around me
