Hi folks. New owner of a 2001 Tahoe. 196k miles on it. A gift from the mother in law. I have never owned a US truck before and need some guidance. I think the only thing she changed on it was the oil and an occasional flat tire. Brakes are almost gone, steering is a bit wobbly, kills gas and probably a lot needs to be changed underneath the hood and all. Any ideas or suggestions as to what should I take care of first would be greatly appreciated.
