Every now and then I get the urge to buy something smaller, more fuel efficient, and newer, but then I read all the horror stories about crappy engines, failed transmissions and nightmare dealer service and I thank God for my Suburban. I've had this truck since 03/2001, and it has been nothing but awesome. I have fixed a couple of leaks, the door hinges, replaced radiator, and replaced the water pump in nearly 6 years. Reliable, strong, and comfortable are trademarks of this truck. MPG isn't great, but who buys a Suburban for MPG. Drop your foot and hold on. You can't kill this truck. I love it.
The power, the room, and the quality
Side curtain airbags (couldn't think of anything else)
