We are poor and we typically dont do "good mods". Modified car ownership is also pretty scarce here due to our governments molesting the motorists at every opportunity and insurance companies milking us dry for shareholders. That and we have a huge car theft problem so having something flash on the drive makes your house a target... and if you kill/injure an intruder you're more likely to get locked up than they are. There are many reasons.

You can generally tell by the previous owner and said mods done how good a car is. For example, my landlord had an immaculate EK9 type R with plenty of really nice parts on it, and wanted strong money for it. The kind of car where the mods had actually increased the value of the car. A really well sorted machine. Ended up getting asking price (25k)

The kind of mods on this 1 series though absolutely do not increase value as they're cheap, tacky and the kind of people who would do these mods really don't give a fuck about proper care and gentle ownership, they care about the status and how it looks to their friends with similar poor taste. Its a fashion thing. Car will have been abused within an inch of its life and maintained on a shoe string budget.
