As mentioned, you are on the right site for info, I researched pretty hard here before buying. I did print out a couple of checklists from other sites before inspecting mine so I'll link you to them when I get home. Off the top of my head:
- Coolant smell from heater = leaky heater core, has it already been replaced
- Check CV boots for wear
- check for front brake rotor warpage, brake gently at any speed to check
- Does it have black or silver brake calipers, silver are less prone to warping the rotors
- If it's a Limited do all the electric gizmos like heated seats etc still work
- Is it Quadra DRIVE (not Quadra Trac), if so extra traction offroad
