I paid $14500 for a 2005 Sport V8 4x4, with 177,000mi.
That's high at first glance, but it has the following mods installed only 4 months / 4000mi ago:
- Lifted 4in with Yotamafia Bilstein 6112/5160 combo
- Rear coils - OME 895 medium duty
- SPC adjustable upper control arms
- Rims = Method 312
- Tires = Falken WILDPEAK M/T01 LT285/70R17/ 113Q
The mods + labor was $5600. And the mechanic that did a pre-purchase inspection on it confirmed the quality and condition of these components. Other aspects of the inspection also came back extremely clean.
All in all, without considering the mods (which I probably would have eventually gotten something similar), I paid $9000 for a very clean 2005 V8 at 177,000 miles.
I think I did okay, especially considering the California tax :-)
