Found a truck I like at CarMax, but want to know if they are a good place to buy from. I bought a car 10 years ago from them, but wrecked it on the highway after a couple months, so I really can't tell if it was worth it or not. Anyone have experience with them? Also, they offer a 5 year bumper-to-bumber warranty for about $1,500 (more with the financing of course), but the one I'm looking at is only 2 years old with 47k miles. Wouldn't the manufacturer's warranty cover most major stuff anyway? If not, is getting it from CarMax a good idea?
