That's the big question. Cars can be replaced.
As for that, I never got into the idea of leasing. If I'm paying that much money for something, I want to own it when I'm done. Had pretty good luck with my first two cars -- both three years old when I got them, but in good shape and with low-to-moderate mileage. (This dealership sends most of its trade-ins to auction, keeping only the cleanest ones.) Decided to go new the last time, but only because I could get the GM employee discount, and plan on driving this one till it drops.
