A couple of basic questions about the 100 series Land Cruiser


So now that I've had my 1998 Land Cruiser a couple weeks I'm still trying to get a feel for it and I have a couple of questions I'm hoping you can answer.

First, what features were standard, common, and rare?

My vehicle has

Leather seats
Locking differential (electronic?)
Powered sunroof
Powered rear window louvers
Third row seat
18" wheels
Roof rack

I'm guessing most of these are standard?

Second, what are some of the most common maintenance issues I should be aware of and look out for? Are there any simple fixes or modifications that people commonly do that are low cost/no cost?
