If I was to give up my cars I could move out tomorrow with spare cash to save etc. But as Most of my expenditure is on my cars, I could scrape by with £20-40 left a week for saving or special occasions but that would mean no holidays, cars shows, evenings out etc etc. So for now whilst I dont need to move out I'm not going to.  Im a bit like you im in a 4 bed house my room is nearly as big as some other peoples single bed flats anyway. Sofa 40" tv on stand drumkit, doublebed Shit loads of car parts and still have plenty of space!  I have a separate shower/toilet to my rents and very rarely get nagged, I can go days without seeing them as it is anyway. So for me moving out seems pointless until I have to!
