CO Defender 
2004 Nissan Armada SUV LE 4WD 4dr SUV (5.6L 8cyl 5A)
Worth the Initial Investment
 I've had The Tank for almost 6 years now, and the first 95K were absolutely trouble free.  Since then, I've replaced the radiator core, A/C condenser, and most recently the right side exhaust manifold, not cheap, but considering the 108K of extremely hard driving, and $4K price tag for repairs, it's been well worth it.  I'm on my 3rd set of tires (last two Bridgestone)...fuel economy is still brutal, but considering 6 years and over 100K, I'd buy another if Nissan would continue to build them.
