Looking at 1998 Landcruiser 60K miles

Hi guys,

I am looking at a 1998 Landcruiser with 60K miles (4.7 L engine), which has been well-maintained and need some advices:

- Is this car AWD ALL the time or I have option of engaging and disengaging the AWD (to save gas in the summer)?
- Reliability?
- Transmission Drivetrain problem?
- Engine problem?
- Ease of DIY tune-up (I am mechanically inclined and can do tune-up on most cars)

- Exhaust problem?
- Rust problems?

TIA
