Nothing wrong with a POS to deal with the traffic, dings and dents and horrible drivers. Ill save my nice cars for the weekend cruises. no need to go ****ing up a nice car with daily driving duties.
Depends on where you live I guess. I don't really have heavy traffic to deal with (rip up and down the garden state parkway doing 80mph every day) and I don't commute to any major cities. I know it'd be more responsible of me to get a civic and get 30+MPG on the highway every day but holy shit I would just hate myself day in and day out.
My beater BMW is pretty fun for an old car, it has some options that some cars today still don't have (power headrests, woo) but its cheap enough and the paint sucks enough that I don't have to worry about door dings.
