I know what you mean . . . I normally keep my vehicles 11 years (on average) and I can pretty much figure the price goes up about $1000/year.
I've never had a car payment - I always pay cash. The way to do it is:
1) Drive your vehicle into the ground. I don't mean abuse it, keep doing proper maintainence, but don't be seduced by style, or "keeping up with the Joneses."
2) Even when your vehicle is paid off, keep making those monthy payments . . . . only make them to yourself. By the time you buy another vehicle, you should have enough to pay cash.
3) If you pay cash . . . on the day you buy a new vehicle, start saving for your
next vehicle.
