Car & internet time has certainly hurt my relationship with my wife at times. Obviously, if you can work out a fair compromise for everything you need to, then I think many people would like to see you keep the Contour(s). But if you cannot limit yourself with the temptation (I know it is very hard so don't think of it as an insult), sell the car and move on. There are many more improtant things in life. There are lots of cars out there and you'll have plenty more years left to mess with them.
