i've bought two cars i sold back. ended up parting them both out.... the idea of having them back was better than actually having them back.
the mustang is just one of the toys. still have the 70 dart but you ignored that part of my signature. :)
guess some get all sentimental over their cars.. not me. they are toys. i get to a point and i get bored and move on. so yes you can completely get out of the car hobby today and be full in in a few years. its easy to do and i have done it a couple of times.
